Pins description
Pin n°
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.
9
VSEN
Regulated voltage sense pin for OVP and UVP protections and PGOOD. Connect to the
output regulated voltage, or to the output resistor divider if the regulated voltage is higher than
the reference.
10
PGOOD
Open drain output set free after SS has finished and pulled low when VSEN is outside the
relative window. Pull up to a voltage equal or lower than VCC. If not used it can be left
floating.
