概述
The TPW20400xQ is a 400-mΩ 2/4-channel high-side isolation/protection power switch series with internal current limiting and diagnostics. The TPW20400xQ is AEC-Q100 qualified and can increase the diagnostic coverage to achieve ASIL-B compliance.
The TPW20400xQ input voltage operating range is from 3 V to 15 V, with an absolute maximum rating of 20 V. The VDD range is from 3 V to 5.5 V, with an absolute maximum rating of 6 V.
The TPW20400xQ is equipped with high-precision current sensing capabilities. It offers a current sense accuracy of ±8% from 300 mA to 600 mA. This accurate current sensing enables easy identification of load status and measurement of load current.
The TPW20400xQ integrates full fault diagnostics and device protection to prevent the device damage from short-circuit to the battery, short-circuit to ground, input over/under voltage, output over/under voltage, over current and over temperature.
The TPW20400xQ provides and enables input and I2C interface to read the diagnostic status of the device. It integrates an 8-bit ADC to read the current of each channel. The current limit ratio can also be configured, and the status, including OTP warning, can be read for each channel through the I2C interface. Each channel can also be turned on/off by I2C.
The TPW20400xQ is designed to operate within the ambient temperature range from −40°C to +125°C.
