Description

The 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.

Features

■ 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 32 V

■ Real time diagnostic functions:

– Output shorted to GND

– Output shorted to VS

– Open load detection in ON and OFF condition

– Overtemperature detection

■ Device protection functions:

– Overload disable

– Selective thermal shutdown

– Signal- and Power-Ground-loss shutdown
