PIN FUNCTION DESCRIPTION
ver. A, B, C, D ver. Q Pin Name Description
1 1 VCC Supply voltage pin
2 2 MIN_TOFF Adjust the minimum off time period by connecting resistor to ground.
3 3 MIN_TON Adjust the minimum on time period by connecting resistor to ground.
4 4 LLD This input modulates the driver clamp level and/or turns the driver off during light load
conditions.
5 NC Leave this pin opened or tie it to ground.
6 6 CS Current sense pin detects if the current flows through the SR MOSFET and/or its body
diode. Basic turn−off detection threshold is 0 mV. A resistor in series with this pin can
decrease the turn off threshold if needed.
7 7 GND Ground connection for the SR MOSFET driver, V
CC
decoupling capacitor and for mini-
mum on and off time adjust resistors and LLD input.
GND pin should be wired directly to the SR MOSFET source terminal/soldering point
using Kelvin connection. DFN8 exposed flag should be connected to GND
8 8 DRV Driver output for the SR MOSFET
5 MAX_TON Adjust the maximum on time period by connecting resistor to ground.
