Chip reset pin

The RSTB pin, active low, can block operation of the device by forcing the digital core in reset state.

After releasing the reset pin, STWBC86 can resume normal operation mode.

GPIOx and INTB pins

The GPIO0 through GPIO7 pins are programmable general-purpose I/O pins. These pins can be configured as

inputs or outputs (push-pull or open-drain) according to the selected function.

The INTB(GPIO6) pin is an interrupt output line that can be associated to any internal interrupt condition and used

to inform the host system about specific events.

5.6

Device protections

Input voltage and input current are monitored by an internal ADC.

Both input voltage and input current can be limited by setting OVP and OCP thresholds.

Exceeding either threshold triggers a corresponding protection.

Internal temperature is also measured using the internal ADC and it's threshold can be set in °C.

When the internal temperature exceeds the set threshold, the OTP protection is triggered.
