4.2. Pin Description
Pin
Name
Description
When SMOD#=HIGH, the low-side driver is the inverse of PWM input. When SMOD#=LOW,
1
SMOD# the low-side driver is disabled. This pin has a 10µA internal pull-up current source. Do not add
a noise filter capacitor.
2
VCIN Linear regulator 5V output. Minimum 1µF X5R/X7R ceramic capacitor to CGND is required.
3
VDRV Linear regulator input. Minimum 1µF X5R/X7R ceramic capacitor to CGND is required.
4
5, 37, 41
BOOT
CGND
Bootstrap supply input. Provides voltage supply to the high-side MOSFET driver. Connect a
bootstrap capacitor from this pin to PHASE.
Ground return for driver IC.
6
GH Gate high. For manufacturing test only. This pin must float: it must not be connected.
7
PHASE Switch node pin for bootstrap capacitor routing; electrically shorted to VSWH pin.
8
NC
No connection. The pin is not electrically connected internally but can be connected to VIN for
convenience.
9 - 14, 42
15, 29 - 35, 43
16 – 28
36
VIN
VSWH
PGND
GL
Input power voltage (output stage supply voltage).
Switch node. Provides return for high-side bootstrapped driver and acts as a sense point for
the adaptive shoot-through protection.
Power ground (output stage ground). Source pin of the low-side MOSFET.
Gate low. For manufacturing test only. This pin must float. It must not be connected.
38
THWN#
Thermal warning flag, open collector output. When temperature exceeds the trip limit, the
output is pulled LOW. THWN# does not disable the module.
Output disable. When LOW, this pin disables the power MOSFET switching (GH and GL are
39
DISB# held LOW). This pin has a 10µA internal pull-down current source. Do not add a noise filter
capacitor.
40
PWM PWM signal input. This pin accepts a tri-state 3.3V PWM signal from the controller.
