L9332Quad intelligent power low side switch
Datasheet - production data
Features Quad power low side driver with 3 A output
current capability Low RDSON typically 200 mΩ and 300 mΩ Tj = 25 °C Internal output clamping structures with
VFB = 50 V for fast inductive load current re
circulation Limited output voltage slew rate for low EMI Protected μP compatible enable and input Wide operating supply voltage range 4.5 V to V Real time diagnostic functions: Output shorted to GND Output shorted to VS Open load detection in ON and OFF
condition Over temperature detection Device protection functions: Overload disable Selective thermal shutdown Signal- and Power-Ground-loss shutdown
DescriptionThe L9332 is a monolithic integrated quad low
side driver realized in an advanced Multipower
BCD mixed technology. The device is intended to
drive valves in automotive environment.
The inputs are μP compatible. Particular care has
been taken to protect the device against failures,
to avoid electromagnetic interferences and to
offer extensive real time diagnostic.
