• General
– Very low standby current
– 3.0 V CMOS compatible input
– Optimized electromagnetic emission
– Very low electromagnetic susceptibility
– Fault reset standby pin (FR_Stby)
• Diagnostic functions
– Proportional load current sense
– High current sense precision for wide range
currents
– Off-state open load detection
– Output short to VCC detection
– Overload and short to ground latch off
– Thermal shutdown latch-off
– Very low current sense leakage
The VPS2535H is a monolithic device made
using STMicroelectronics® VIPower® technology,
intended for driving resistive or inductive loads
with one side connected to ground. Active VCC
pin voltage clamp protects the device against low
energy spikes.
The device integrates an analog current sense
which delivers a current proportional to the load
current.
Fault conditions such as overload,
overtemperature or short to VCC are reported via
the current sense pin.
Output current limitation protects the device in
overload conditions. The device latches off in
case of overload or thermal shutdown.
The device is reset by a low level pass on the fault
reset standby pin.
A permanent low level on the inputs and on the
fault reset standby pins disables all outputs and
sets the device in standby mode.
• Protections
– Undervoltage shutdown
– Overvoltage clamp
– Load current limitation
– Self limiting of fast thermal transients
