Safety system basis chip (SBC) with power management, CAN FD and LIN transceivers

An overcurrent detection is also implemented on the low-side MOSFET, to detect high negative current in

case of output short to the battery. In this case, both V1OC_I flag and V1_OCLS_I flag are set and the device

transitions to fail-safe depending on OTP configuration using V1_OCLS_EN_OTP.

Input voltage range

HVBUCK output voltage regulation is guaranteed for a minimum V1_IN, which depends on IBUCK current

load. To ensure HVBUCK output voltage regulation, V1_IN should be above (VBUCK + ((Max(RLS_BUCK) +

Max(RDCR_LBUCK)) x IBUCK)) / DCMAX_DROP the maximum duty cycle in Dropout mode.

For example, with RDCR_LBUCK = 200 mΩ at IBUCK = 400 mA with VBUCK = 3.3 V, the minimal V1_IN is VBUCK +

527 mV.

Thermal shutdown

When a thermal shutdown is detected, the regulator is disabled and V1TSD_I flag is generated.
