Description
The VN31SP is a monolithic device made using STMicroelectronics VIPower Technology, intended for driving resistive or inductive loads with one side grounded. Built-in thermal shut-down protects the chip from over temperature and short circuit. The open drain diagnostic output indicates: open load in off state, and in on state, output shorted to VCC and overtemperature. Fast demagnetization of inductive loads is archivied by negative (-18V) load voltage at turn-off. ® 1 10 PowerSO-10 (*) In = Nominal current according to ISO definition for high side automotive switch (see note 1) (#) The maximum continuous output current is the the current at Tc = 85 oC for a battery voltage of 13V which does not activate self protection. 1/9
