**MSKSEMI** · Brushed DC Motor Drivers · SOT-23-6

AP1511B-MS from MSKSEMI, in a SOT-23-6. 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 | CE | output | External capacitor pin that sets the on-time of the forward and reverse drive cycles, per the datasheet's pin table (datasheet types this pin as O). |
| 2 | GND | power_in | Power ground for the device. |
| 3 | FBC | input | Logic input for the PWM interface, rated for 0 to 5.0V operation with a 1.50V minimum high-level input and 0.8V maximum low-level input, and compatible with 1.8V/3.3V/5.0V I/O. |
| 4 | OUT1 | output | H-bridge output OUT1, rated for continuous output current up to 1.2A and peak current up to 2.5A. |
| 5 | VM | power_in | Supply input rated 2.0 to 7.5V, which must have a 10uF or larger capacitor connected between VM and GND. |
| 6 | OUT2 | output | H-bridge output OUT2, rated for continuous output current up to 1.2A and peak current up to 2.5A. |
