Automotive, 60-V, 6-A, 30-mΩ, one-channel smart high-side switch with adjustable current limit TPS1HTC30-Q1 is a single-channel, smart high-side switch, with integrated NMOS power FET and charge pump, designed to meet the requirements of 24-V automotive battery systems. The low RON(30 mΩ) minimizes device power dissipation driving a wide range of output load current up to 6-A DC, and the 60- V DC operating range improves system robustness. The device integrates protection features such as thermal shutdown, output clamp, and current limit. These features improve system robustness during fault events such as short circuit. TPS1HTC30-Q1 implements an adjustable current limiting circuit that improves the reliability of the system by reducing inrush current when driving large capacitive loads and minimizing overload current. The device also provides an accurate load current sense that allows for improved load diagnostics such as overload and open-load detection enabling better predictive maintenance. TPS1HTC30-Q1 is available in a small 14-pin, 4.40- mm × 5.0-mm HTSSOP leaded package with 0.65- mm pin pitch minimizing the PCB footprint. • Single-channel smart high-side power switch for 24-V automotive systems with full diagnostics • Wide operating voltage range: 6 V to 60 V – OVP protection: 66 V • Low RON: 30-mΩ typical, 55-mΩ maximum • Low standby current: < 0.5 µA • Low quiescent current (Iq): < 2 mA • Improve system level reliability through adjustable current limiting – Current limit: 2 A –16 A • Accurate current sensing: ±4% at 1 A • Protection – Overload and short-circuit protection – Integrated inductive discharge clamp – Undervoltage lockout (UVLO) protection – Loss of GND, loss of supply protection – Reverse battery protection with external components • Diagnostics – On and off state output open-load and short-tobattery detection – Overload and short to ground detection – Absolute and relative thermal shutdown detection • Functional Safety-Capable – Documentation available to aid functional safety system design • Operating junction temperature: –40 to 125°C • Input control: 1.8-V, 3.3-V and 5-V logic compatible • Integrated fault sense voltage scaling for ADC protection • Qualifications – AEC-Q100 qualified for automotive applications • Temperature grade 1: –40°C to +125°C, TA • 14-pin thermally-enhanced TSSOP package TPS1HTC30AQPWPRQ1 #CommonPartsLibrary #IntegratedCircuit

Accelerometer X, Y, Z Axis ±2g, 4g, 8g, 16g 0.05Hz ~ 1.6kHz 14-LGA (3x5) The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Free-fall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins. An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation. The ADXL345 is supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-lead, plastic package. ► Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical) ► Power consumption scales automatically with bandwidth ► User-selectable resolution ► Fixed 10-bit resolution ► Full resolution, where resolution increases with g range, up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor in all g ranges) ► Embedded memory management system with FIFO technology minimizes host processor load ► Single tap/double tap detection ► Activity/inactivity monitoring ► Free-fall detection ► Supply voltage range: 2.0 V to 3.6 V ► I/O voltage range: 1.7 V to VS ► SPI (3- and 4-wire) and I2C digital interfaces ► Flexible interrupt modes mappable to either interrupt pin ► Measurement ranges selectable via serial command ► Bandwidth selectable via serial command ► Wide temperature range (−40°C to +85°C) ► 10,000 g shock survival ► Pb free/RoHS compliant #CommonPartsLibrary #IntegratedCircuit #Sensor #Transducer #Motion-Sensor #Accelerometer #ADXL345
