Pin

Description

RESET\FAULT

1

Open drain output, active low. It generates a 57 ms pulse if a fault condition is detected or

when HW_RESET\USB is pulled high

VBAT

2

Battery supply voltage. Bypass this pin to GND with a 1 µF ceramic capacitor

AGND

3

Analog GND. Connect it to a dedicated ground path

TPF

4

T1 oscillator programming pin. Connect a resistor to GND, to achieve a frequency ranging from

100 kHz to 400 kHz

T1P1

5

T1 timer programming pin. Connect to VBAT, GND or floating to select T1 prescaler (hard

wired). See Figure 5. Timer configuration truth table

T1P2

6

T3P

7

T3 timer programming pin. Connect to VBAT, GND or floating (hard wired). See Figure 5. Timer

configuration truth table

PGND

8, 9, 10

Power ground (internal N-channel power MOS source terminal)

PWR

11, 12, 13 Input power voltage (internal N-channel power MOS drain terminal)

GDRV

14

Gate driver output. Leave floating if it is not used

HW_RESET\USB

15

Input hardware reset. Do not leave floating. If it is not used, put to GND

PWM

16

Input control signal, 4 Hz to 5 kHz, 30%-100% duty cycle

GND

EXP

Exposed pad, connect to thermal ground plane
