Power Switch/Driver 1:1 N-Channel 1.35A 28-WQFN (4x5) The TPS274160 device is a smart high-side switch with four integrated 160-mΩ NMOS power FETs and a chargepump to drive the gates. The device offers robust protection and diagnostic features to drive various loads (inductive, capacitive, and resistive) such as low wattage bulbs, LEDs, relays, solenoids, heaters, and sub-modules. The part enables flexible, multi-channel output configurations through paralleling channels and is in a very small WQFN package to enable usage in space constrained applications. The device is protected against short circuit events and over-temperature events, safely shutting off the output during fault events. The device also implements an external adjustable current limiting feature. This feature improves the reliability of the system by reducing inrush current when driving large capacitive loads and minimizing overload current thereby eliminating system supply brown out condition. The device also integrates diagnostic features like output current monitoring (version B) and open load detection to enable improved intelligence in modules and to enable predictive maintenance functionality. • Quad-channel 160-mΩ smart high-side switch • Wide DC operating voltage range: 5 V to 36 V – 50-V absolute maximum voltage • Accurate adjustable current limiting (250 mA to 4 A) • Intelligent diagnostic features – TPS274160A: Open-drain fault output – TPS274160B: Analog current sense – Open-load or short to supply detection in the off-state • Robust protection features – Short-circuit protection – Inductive load flyback clamp – Undervoltage lockout (UVLO) protection – Loss of GND protection • Excellent ESD protection on VS and OUT pins – ±8/±15 kV IEC 61000-4-2 ESD contact/air discharge • Available in small and 28-pin leadless QFN packages • Functional Safety-Capable – Documentation available to aid functional safety system design 2 Applications • Digital output modules • Standalone remote I/O • Motor drives • Solenoid or valve drive #TexasInstruments #TPS274160BRLHR #HighSideSwitch #SmartSwitch #IndustrialAutomation #PowerManagement #LoadDriver #CurrentLimiting #ProtectionIC #IndustrialControl #RemoteIO #SolenoidDriver #MotorDrive #EmbeddedSystems #ElectronicsDesign

Half Bridge (2) Driver DC Motors, General Purpose NMOS, Power MOSFET 24-VQFN (4x4) The DRV8770RGER is a high-voltage brushed DC motor gate driver integrated circuit manufactured by Texas Instruments, designed to drive external N-channel power MOSFETs configured in a dual half-bridge topology for use in brushed DC motor control, stepper motor drive, solenoid actuation, and other inductive load switching applications. Rather than integrating the power stage transistors directly within the IC, the DRV8770 functions as a gate driver, providing the gate voltage and current needed to fully and rapidly switch external discrete power MOSFETs, which allows the designer to choose power devices appropriate to the specific voltage and current requirements of their motor or load without being constrained by the internal power stage of an integrated motor driver. The DRV8770 delivers two half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The integrated bootstrap diode and external capacitor generate the correct gate drive voltages for the high-side MOSFETs, while the GVDD rail drives the gates of the low-side MOSFETs. This bootstrap architecture eliminates the need for an external isolated gate drive power supply for the high-side switch, simplifying the overall power stage design significantly compared to approaches that require separate high-side power supply generation. This device decreases system component count, reduces PCB area, and saves cost by integrating two independent half-bridge gate drivers and bootstrap diodes. digikeyTME The high-side and low-side gate drivers can drive source and sink currents sufficient for fast, efficient switching of external power MOSFETs, with total average output current capability defined in the datasheet. The asymmetric source and sink current capability is a deliberate design choice reflecting the typical requirements of power MOSFET switching, where rapid turn-off is often more critical than turn-on speed for preventing shoot-through and managing switching losses in bridge circuits. Small propagation delay and delay matching specifications minimize the dead-time requirement, which further improves efficiency. TMEFarnell The high voltage tolerance of the gate drive pins improves system robustness. The SHx phase pins can tolerate significant negative voltage transients, while the high-side gate driver supply can support higher positive voltage transients on the BSTx and GHx pins. This enhanced transient tolerance is essential in motor drive applications where inductive switching generates voltage spikes and negative voltage excursions on the switch node that would damage less robust gate driver designs. An input deglitcher prevents high-frequency noise on the input pins from affecting the output state of the gate drivers, protecting against inadvertent switching caused by electrical noise on the control interface lines. FarnellAllDataSheet The device can drive one or two DC brush motors, one stepper motor, solenoids, or other inductive loads. This versatility makes it suitable across a broad range of actuator types within the same hardware platform, allowing a single PCB design to serve multiple product variants by simply changing the connected load and the firmware control scheme. Undervoltage protection is provided for both low-side and high-side through GVDD and BST undervoltage lockout, preventing the external power MOSFETs from operating with insufficient gate drive voltage, which would cause them to enter a linear operating region with excessive power dissipation and potential thermal damage. digikeyFarnell The DRV8770RGER is housed in a compact VQFN twenty-four-pin surface-mount package, suited to space-constrained motor drive PCB layouts, and is rated for operation across an extended industrial temperature range.
