Description

1

ADCMON: VADC monitor flag (reset)

2

RSTN1: VDD1 monitor flag (reset)

3

RSTN2: VDD2 monitor flag (reset)

4

WAKE_EXT : Wake-up pin (to be > 3.25 V to enable power supply)

5

WDO: Watchdog output (output is driven low

in case of watchdog fault)

6

STBY: Standby input (The state can be entered by ACTIVE state by rising STBY pin. Depending on the
active VDD regulators (i.e. the regulators which have not been disabled in the application), the low power
mode is managed in a different way). Please refer to L9001 Datasheet for further information

7

WDI: Windows watchdog input. Please refer to L9001 Datasheet for further information

8

TWN: Thermal warning flag output

9

GND : Ground
