7.4.1.2.3 Heater MOSFET Open Load Detection

Off-state open-load monitoring is done by comparing the voltage difference SH_HS node when pulled-up by current source against open-load threshold voltage VOL_HEAT. If SH_HS voltage exceeds the open-load threshold VOL_HEAT for longer than filter time tOL_HEAT, the open-load bit HEAT_OL is set. Open-load monitor is controlled by bit HEAT_OLP_EN.

Note: The heater open load diagnostics will only work when the heater configuration is disabled, where bits HEAT_OUT_CNFG must be 00b.
