DESCRIPTION

The STPIC44L02 is a low-side predriver that provides serial and parallel input interfaces to control four external FET power switches.
It is mainly designed to provide low-frequency switching, inductive load applications such as solenoids and relays. Fault status is available in a serial-data format. Each driver channel has independent off-state open-load detection and on-state shorted load short to battery detection
