Pin
Name
Function
1, 6, 51, A
CGND
IC Ground. Ground return for driver IC.
2
HSEN
High Side FET Enable. Must be connected to BOOT pin.
3, 7, 52-54
NC
No connect
4
VCIN
IC Supply. +5V chip bias power. Bypass with a 1μF ceramic capacitor.
5
BOOT
Bootstrap Supply Input. Provides voltage supply to high-side MOSFET driver. Connect
bootstrap capacitor.
21, 40-50, C
VSWH
Switch Node Input. SW Provides return for high-side bootstrapped driver and acts as a
sense point for the adaptive shoot-thru protection.
8, 9, 11-20, B
VIN
Power Input. Output stage supply voltage.
10
TEST PAD 1
For manufacturing test only. HDRV pin. This pin must be floated. Must not be connected to
any pin.
22-38
PGND
Power ground. Output stage ground. Source pin of low side MOSFET(s).
39
TEST PAD 2
For manufacturing test only. LDRV pin. This pin must be floated. Must not be connected to
any pin.
55
DISB
Output Disable. When low, this pin disable FET switching (HDRV and LDRV are held low).
56
PWM
PWM Signal Input. This pin accepts a logic-level PWM signal from the controller.
