side MOS is shorted to ground

'!0'03ꢀꢀꢁꢂꢁ

 2 fire enable inputs

LQFP64 (10x10x1.4mm)

 5.5 MHz SPI interface

 Low voltage internal reset

 2 kV ESD capability on all pins

 Package: LQFP64

Features

 Technology: ST proprietary BCD5 (0.65µm)

 RoHS compliant

 4 deployment drivers with SPI selectable firing

current and times

Description

 Capability to deploy the squib with 1.2 A

(min)/2 ms, 1.75 A (min)/1.0 ms and 1.75 A

(min)/0.65 ms between VRES of 7 V to 37 V

The L9660 is intended to deploy up to 4 squibs.

Squib drivers are sized to deploy 1.2 A minimum

for 2 ms, 1.75 A minimum for 1 ms and 1.75 A

minimum for 0.65 ms during load dump along with

1.5 A minimum for 2 ms for VRES voltages less

than 25 V.

 Capability to deploy the squib with 1.5 A

(min)/2 ms between VRES of 7 V to 25 V

 Firing capability to deploy all channels

simultaneously

Full diagnostic capabilities of the squib interface

are provided.

 Independently controlled high-side and low-

side MOS for diagnosis
