Remarks
Should be connected to PGND externally
when SMOD# is “low” the GL is OFF
5V bias voltage for the internal logic.
High & Low Side gate drive 5V
Connect to boot capacitor
pin for monitoring gate of HS FET
Internally connected to VSWH pin
Can be connected to any potential
connection to the drain of the HS FET
high current output switch node
All of these pins must be connected to the power GND plane
through multiple, low inductance vias.
pin for monitoring gate of LS FET
pull to GND to disable the IC
the three-state PWM input is compatible with 3.3V and 5V
