概述

The TPS42Q20Q is a 160-mΩ 4-channel high-side power switch product with AEC-Q100 qualified.

The TPS42Q20Q has a wide voltage operating range of 3.5 V to 40 V, with an absolute maximum rating of 45 V. This flexibility makes it suitable for various automotive applications in different conditions.

The TPS42Q20Q is equipped with high-precision current sensing capabilities. It offers a current sense accuracy of 3% for the loads of 500 mA or greater, and 8% for the loads of 50 mA or greater. This accurate current sensing enables easy identification of load status and measurement of load current.

The TPS42Q20Q integrates full fault detection and device protection to prevent the device damage from open load, overload, over temperature, short-circuit to the battery, short-circuit to ground, reverse battery, loss of ground, loss of power supply and voltage clamp. With all these protection functions, this device is suitable for different resistive, inductive and capacitive loads.

The TPS42Q20Q is designed to operate within the ambient temperature range from −40°C to +125°C. Moreover, the TPS42Q20Q provides a thermal-enhanced ETSSOP28 package to enable sustained operation despite significant dissipation across the device.
