VPS2535HTR

Power Distribution Switches, Load Drivers Overview

The VPS2535HTR is a monolithic double-channel high-side driver manufactured using STMicroelectronics VIPower technology. It is designed for driving resistive or inductive loads with one side connected to ground. The device integrates an analog current sense pin that delivers a signal proportional to the load current, enabling precise monitoring. Active VCC voltage clamping protects against low-energy spikes, while output current limitation safeguards against overload conditions. Fault states including overload, overtemperature, and short-to-VCC are reported via the current sense pin. The unit latches off during critical faults and resets via the fault reset standby pin.
