AT8236-MS

MSKSEMI · Brushed DC Motor Drivers · ESOP-8

AT8236-MS from MSKSEMI, in a ESOP-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 GND power_in Logic ground; connect to board ground.
2 IN2 input Logic input that controls the H-bridge output, with a 100 kΩ internal pulldown to GND.
3 IN1 input Logic input that controls the H-bridge output, with a 100 kΩ internal pulldown to GND; logic inputs are rated to 6 V absolute maximum.
4 VREF power_in Analog reference input; apply a voltage between 0.3 V and 5 V to set the current-regulation level.
5 VM power_in Motor and device supply, 6.5 V to 40 V; connect a 0.1 µF bypass capacitor to ground plus sufficient bulk capacitance rated for the VM voltage.
6 OUT1 output H-bridge output; connect directly to the motor or other inductive load.
7 ISEN passive High-current ground path; connect to a low-value, high-power sense resistor to ground for current regulation, or directly to ground if current regulation is not used.
8 OUT2 output H-bridge output; connect directly to the motor or other inductive load.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
