MAX4427ESA+T

Analog Devices Inc Maxim Integrated · Gate Drivers · SO-8

MAX4427ESA+T from Analog Devices Inc Maxim Integrated, in a SO-8. 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 N.C. unconnected No internal connection on the MAX4427 SO package; the datasheet pin configuration shows it as N.C.
2 INA input Channel A TTL/CMOS-compatible input with logic-1 minimum of 2.4V and logic-0 maximum of 0.8V; it must not stay between VIH and VIL for more than 50ns, and unused inputs should be tied to ground.
3 GND power_in Ground return for the device; the datasheet requires ground drops to be minimized because they degrade delay and transition times.
4 INB input Channel B TTL/CMOS-compatible input with logic-1 minimum of 2.4V and logic-0 maximum of 0.8V; it must not stay between VIH and VIL for more than 50ns, and unused inputs should be tied to ground.
5 OUTB output Channel B noninverting MOSFET driver output capable of 1.5A peak output current at VDD = 18V.
6 VDD power_in Supply input with an operating range of 4.5V to 18V; the absolute maximum supply rating is 20V and it should be bypassed with 4.7µF plus 0.1µF close to the device.
7 OUTA output Channel A noninverting MOSFET driver output capable of 1.5A peak output current at VDD = 18V.
8 N.C. unconnected No internal connection on the MAX4427 SO package; the datasheet pin configuration shows it as N.C.
