概述

The TPS42Q20 is a 160-mΩ 4-channel high-side power switch product.

The TPS42Q20 has a wide voltage operating range of 3.5 V to 40 V, with an absolute maximum rating of 48 V. This flexibility makes it suitable for different conditions.

The TPS42Q20 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 TPS42Q20 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 TPS42Q20 is designed to operate within the junction temperature range from −40°C to +125°C. Moreover, the TPS42Q20 provides a thermal-enhanced ETSSOP28 package to enable sustained operation despite significant dissipation across the device.
