Pin description
Pin n°
Name
Description
1BOOT1
Channel 1 HS driver supply. Connect through a capacitor (100 nF typ.) to
PHASE1
Needed external bootstrap diode.
The device implements Vin detections through this pin. See “vin detection”
section for details. A small resistor in series to the boot diode helps in reducing
Boot capacitor overcharge (see reference schematic).
2UGATE1
Channel 1 HS driver output. It must be connected to the HS1 MOSFET gate.
A small series resistors helps in reducing device-dissipated power.
3POK
Power OK
Open drain output sets free after soft start has finished and pulled low when
triggering any latched protection (OVP, UVP, OCP average).
Pull up to a voltage lower than 3.3 V (typ), if not used it can be left floating.
4
SCL
Serial BUS clock input.
5
SDA
Serial BUS data input.
