VB_REF_FAULT

I

Voltage reference for internal OC detector input or digital input from

external OC detector (V3V3V referred). 5V tolerant.

D4

PSWn

O External charge pump control, active low. 5V tolerant, open drain.

F5

XI

I External clock input (1V8VIO referred). Crystal terminal (on request).

F6

XO

O

Left floating or connect to GND when external clock signal is used.

Crystal terminal on request.

F3

VBAT

PWR

Battery power input for the LDO (3 V – 4.5 V). Bypass VBAT to GND with

a 1µF capacitor.

E3

3V3V

PWR 3.3V LDO output. Bypass 3V3V to GND with a 1.5µF capacitor.

E6

1V2V

PWR 1.2V LDO output. Bypass 1V2V to GND with a 1.5µF capacitor.

C2

RREF

I/O Reference resistor (12kΩ ±1%).
