NCP4306DAHZZAASNT1G

onsemi · AC-DC Controllers And Regulators · TSOP-6

NCP4306DAHZZAASNT1G from onsemi, in a TSOP-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DRV output Driver output for the SR MOSFET, rated for 7 A peak sink and 2 A peak source drive capability per the features list, with DRV clamp 10 V for this OPN (postfix 2 = A).
2 GND power_in Ground connection for the SR MOSFET driver and VCC decoupling capacitor, which should be wired directly to the SR MOSFET source using a Kelvin connection.
3 CS input Current sense pin detects whether current flows through the SR MOSFET and/or its body diode, and is rugged up to 200 V.
4 MIN_TON input Adjusts the minimum on-time period by connecting a resistor to ground; for this OPN the MIN_TON is set externally (postfix 4 = Z).
5 MIN_TOFF input Adjusts the minimum off-time period by connecting a resistor to ground; for this OPN the MIN_TOFF is set externally (postfix 5 = Z).
6 VCC power_in Supply voltage pin, with an operating voltage range up to VCC = 35 V.
