Description
The device is a double channel high-side driver
manufactured using ST proprietary VIPower®
technology and housed in PowerSSO-12
package. The device is designed to drive 12 V
automotive grounded loads through a 3 V and
5 V CMOS compatible interface, providing
protection and diagnostics.
The device integrates advanced protective
functions such as load current limitation, overload
active management by power limitation and
overtemperature shutdown.
A current sense delivers high precision
proportional load current sense in addition to the
detection of overload and short circuit to ground,
short to VCC and off-state open-load.
A sense enable pin allows off-state diagnosis to
be disabled during the module low-power mode
as well as external sense resistor sharing among
similar devices.
