DESCRIPTION
The VN21SP 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

of inductive loads is archivied by negative (-18V)
load voltage at turn-off.
(*) 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.
