Pins description
Pin #
Name
Function
1BOOT
HS driver supply.
Connect through a capacitor (100 nF) to the floating node (LS-Drain) pin
and provide necessary bootstrap diode from VCC.
2
PHASE
HS driver return path, current-reading and adaptive-dead-time monitor.
Connect to the LS drain to sense
RDS(on) drop to measure the output
current. This pin is also used by the adaptive-dead-time control circuitry to
monitor when HS MOSFET is OFF.
3
UGATE
HS driver output. Connect directly to HS MOSFET gate.
4
LGATE / OC
LGATE. LS driver output. Connect directly to LS MOSFET gate.
OC. Over Current threshold set. During a short period of time following
VCC rising over UVLO threshold, a 10
μA current is sourced from this pin.
Connect to GND with an ROCSET resistor greater than 5 kΩ to program OC
Threshold. The resulting voltage at this pin is sampled and held internally
as the OC set point. Maximum programmable OC threshold is 0.55 V. A
voltage greater than 0.6 V activates an internal clamp and causes OC
threshold to be set at the maximum value.
5GND
All internal references, logic and drivers are connected to this pin.
Connect to the PCB ground plane.
6VCC
Device and drivers power supply.
Operative range from 5 V to 12 V. Filter with at least 1 nF MLCC to GND.
7
COMP / DIS
COMP. Error amplifier output. Connect with an RF - CF // CP to FB to
compensate the device control loop.
DIS. The device can be disabled by pushing this pin lower than 0.75 V (typ).
Setting free the pin, the device enables again.
8FB
Error amplifier inverting input.
Connect with a resistor RFB to the output regulated voltage. Output resistor
divider may be used to regulate voltages higher than the reference.
