Figure 15. Overcurrent Profile with OCHI bit set to ‘1’

The wire harness is protected by one of four possible current levels in steady state, as defined in Table 17.

Bit D0 (OC_mode_sel) allows to select the overcurrent mode, as described Table 18.

Address 00101—GLObal configuration regIster (GCR)

The GCR register allows the MCU to configure the device through the SPI.

Bit D8 allows the MCU to enable or disable the VDD failure detector. A logic [1] on VDD_FAIL_en bit allows switch of the outputs

HS[0:1] with PWMR register device in Fail-safe mode in case of VDD < VDD(FAIL).

Bit D7 allows the MCU to enable or disable the PWM module. A logic [1] on PWM_en bit allows control of the outputs HS[0:1]

with PWMR register (the direct input states are ignored).

Bit D6 (CLOCK_sel) allows to select the clock used as reference by PWM module, as described in the following Table 19.

Bits D5:D4 allow the MCU to select one of two analog feedback on CSNS output pin, as shown in Table 20.
