MCP14A0303T-E

Microchip Tech · Gate Drivers · SOIC-8

MCP14A0303T-E from Microchip Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ENA input Active-high enable for Driver A. TTL-compatible high-impedance input with hysteresis and an internal pull-up to VDD (~1.8 MΩ typ), so it may be left floating for standard operation. Driving ENA below V_EL (0.8V max) disables Driver A and forces /OUTA low regardless of INA.
2 INA input Control input for Driver A. High-impedance TTL-compatible input with low-voltage thresholds (V_IH=2.0V min, V_IL=0.8V max) and 0.3V hysteresis; input range GND-0.3V to VDD+0.3V.
3 GND power_in Device ground / return for input and output stages. Must have a low-impedance connection to the bias supply return to handle the high peak discharge currents of capacitive gate loads.
4 INB input Control input for Driver B. High-impedance TTL-compatible input with low-voltage thresholds (V_IH=2.0V min, V_IL=0.8V max) and 0.3V hysteresis; input range GND-0.3V to VDD+0.3V.
5 /OUTB output Push-pull gate-drive output for Driver B (inverted relative to INB on the MCP14A0303). Sources/sinks up to 3A peak into an external MOSFET/IGBT gate; R_OH≈2.4Ω, R_OL≈1.6Ω typ at VDD=18V. Rated for 500 mA reverse-current latch-up withstand.
6 VDD power_in Bias supply input for the driver (4.5V-18V operating; 20V absolute max). Must be decoupled to GND with a local low-ESR ceramic capacitor (1 µF
7 /OUTA output Push-pull gate-drive output for Driver A (inverted relative to INA on the MCP14A0303). Sources/sinks up to 3A peak into an external MOSFET/IGBT gate; R_OH≈2.4Ω, R_OL≈1.6Ω typ at VDD=18V. Rated for 500 mA reverse-current latch-up withstand.
8 ENB input Active-high enable for Driver B. TTL-compatible high-impedance input with hysteresis and an internal pull-up to VDD (~1.8 MΩ typ), so it may be left floating for standard operation. Driving ENB below V_EL (0.8V max) disables Driver B and forces /OUTB low regardless of INB.
