Guaranteed by design.
With a nominal squib load, the FET squib driver will not enter thermal shutdown until the driver has been active for a minimum of 2.1 ms.
The individual squib driver thermal shutdown will not affect other squib driver firing ON times. With a shorted squib load, the FET squib
driver will not enter thermal shutdown until the driver has been active for a minimum of 2.1 ms. When the thermal shutdown limit is
exceeded, the FET driver will turn OFF and the thermal status bit will be set to 1. The FET squib driver can be activated through the
arm ire command when the TEMP
RENABLE
(MIN) is reached (thermal shutdown status “0”). Nominal squib load: 2.15
± 0.15
.
Shorted squib load: 0.1
