**Microchip Tech** · Pre-ordered Chips · SOIC-8

MCP14700-E from Microchip Tech, in a SOIC-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 | PHASE | passive | Switch node that returns the high-side gate driver current and connects the high-side MOSFET source to the low-side MOSFET drain; VPHASE is limited to VBOOT - 7V to VBOOT + 0.3V. |
| 2 | PWMHI | input | High-side PWM control input where a logic high drives HIGHDR high; the rising threshold is 1.40V to 1.80V and the falling threshold is 1.10V to 1.30V at VCC = 5.0V, and the pin is internally pulled low. |
| 3 | PWMLO | input | Low-side PWM control input where a logic high drives LOWDR high; the rising threshold is 1.40V to 1.80V and the falling threshold is 1.10V to 1.30V at VCC = 5.0V, and the pin is internally pulled low. |
| 4 | GND | power_in | Ground for the MCP14700 circuitry, which should have a low-impedance connection to the bias supply return because high peak currents flow out of this pin when the low-side MOSFET turns off. |
| 5 | LOWDR | output | Low-side gate drive output that controls the low-side MOSFET, with VLOWDR limited to -0.3V to VCC + 0.3V and 2.0A typical source and 3.5A typical sink peak current. |
| 6 | VCC | power_in | Supply input with an operating range of 4.5V to 5.5V (5.0V typical) and an absolute maximum of +7.0V, requiring a bypass capacitor placed as close as possible to this pin and GND. |
| 7 | BOOT | power_in | Floating bootstrap supply for the high-side driver, rated to a maximum of +36.0V, with a bootstrap capacitor connected between this pin and PHASE. |
| 8 | HIGHDR | output | High-side gate drive output that controls the high-side MOSFET, with VHIGHDR limited to VPHASE - 0.3V to VBOOT + 0.3V and 2.0A typical source and 2.0A typical sink peak current. |
