High-Side Gate Driver IC Non-Inverting 19-VSSOP The TPS48100QDGXRQ1 is an automotive-grade dual high-side gate driver integrated circuit manufactured by Texas Instruments. It is designed to drive external N-channel power MOSFETs configured as high-side switches, providing the gate-drive voltage and current needed to turn the switches fully on and off with controlled timing. The device targets automotive and other harsh-environment power switching applications where a robust, low quiescent current solution is needed to control loads such as motors, relays, solenoids, lighting, and other inductive or resistive loads powered from a vehicle battery rail. As a member of TI's automotive low-IQ high-side driver portfolio, the device is built to tolerate the wide voltage swings and transient conditions characteristic of automotive electrical systems, including load dump events and cold-crank voltage sags, while maintaining very low standby current draw when the driven loads are not active. This low quiescent current characteristic is particularly valuable in always-on automotive modules, where minimizing parasitic battery drain during vehicle-off states is a key design requirement. The device's two independent driver channels operate synchronously, allowing coordinated control of dual high-side switches from a shared set of control and protection circuitry, which is useful in applications such as dual-channel load switching, H-bridge-adjacent driver stages, or redundant power path control. The non-inverting input structure means that the gate driver outputs follow the logic state of the input control signals directly, simplifying integration with microcontroller-based control logic without requiring additional inverting stages. Internally, the device manages the charge pump or bootstrap circuitry needed to generate a gate voltage above the battery rail, which is necessary to fully enhance an N-channel MOSFET configured in the high-side position. This internal voltage generation simplifies the external bill of materials compared to discrete charge-pump driver implementations. The device is qualified to automotive electronics reliability standards, reflecting the rigorous stress testing and quality requirements expected of components used in vehicle electrical and powertrain-adjacent systems. It is housed in a small-outline surface-mount package suited to space-constrained automotive control module designs, and it is supplied in tape-and-reel or cut-tape packaging formats to support both high-volume automated assembly and lower-volume prototyping needs.

555 Type, Timer/Oscillator (Single) IC 2.1MHz 8-PDIP Like the NE555, the TLC555 has a trigger level equal to approximately one-third of the supply voltage and a threshold level equal to approximately two-thirds of the supply voltage. These levels can be altered by use of the control voltage terminal (CONT). When the trigger input (TRIG) falls below the trigger level, the flip-flop is set and the output goes high. If TRIG is above the trigger level and the threshold input (THRES) is above the threshold level, the flip-flop is reset and the output is low. The reset input (RESET) can override all other inputs and can be used to initiate a new timing cycle. If RESET is low, the flip-flop is reset and the output is low. Whenever the output is low, a low-impedance path is provided between the discharge terminal (DISCH) and GND. All unused inputs must be tied to an appropriate logic level to prevent false triggering. • Very low power consumption: – 1mW typical at VDD = 5V • Capable of operation in astable mode • CMOS output capable of swinging rail to rail • High output current capability – Sink: 100mA typical – Source: 10mA typical • Output fully compatible with CMOS, TTL, and MOS • Low supply current reduces spikes during output transitions • Single-supply operation from 2V to 15V • Functionally interchangeable with the NE555; has same pinout • ESD protection exceeds 1000V per ANSI/ESDA/ JEDEC JS-001 • Available in Q-temp automotive – High-reliability automotive applications – Configuration control and print support – Qualification to automotive standards #CommonPartsLibrary #IntegratedCircuit
