ZHCSN08D August 2020 – April 2024 DRV8714-Q1 , DRV8718-Q1
PRODMIX
If the die temperature exceeds the TOTSD thermal shutdown threshold the DRV871x-Q1 detects an overtemperature fault. After detecting the overtemperature fault, the gate driver pull downs are enabled, the charge pump disabled and nFAULT pin, FAULT register bit, and OTSD register bit asserted. After the overtemperature condition is removed the fault state remains latched until CLR_FLT is issued.
On H/W device variants, after the overtemperature condition is removed, the nFAULT pin is automatically cleared and the driver and charge pump automatically reenabled.
