ATD8811TPH

ZHONGKEWEI · Motor Driver ICs · HTSSOP-16

ATD8811TPH from ZHONGKEWEI, in a HTSSOP-16. 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 nSLEEP input Sleep-mode input: high enables normal operation, and low puts the chip into low-power sleep with the H-bridges off.
2 AOUT1 output H-bridge A output 1, which connects to one coil of motor A.
3 AISEN passive H-bridge A current-sense pin, which connects to the sense resistor to ground; tie it directly to ground if current limiting is not used.
4 AOUT2 output H-bridge A output 2, which connects to the other coil of motor A.
5 BOUT2 output H-bridge B output 2, which connects to the other coil of motor B.
6 BISEN passive H-bridge B current-sense pin, which connects to the sense resistor to ground; tie it directly to ground if current limiting is not used.
7 BOUT1 output H-bridge B output 1, which connects to one coil of motor B.
8 nFAULT output Fault output that goes low on over-temperature or over-current; it is open-drain and requires an external pull-up.
9 BIN1 input H-bridge B input 1 logic input that controls BOUT1, with an internal pull-down.
10 BIN2 input H-bridge B input 2 logic input that controls BOUT2, with an internal pull-down.
11 VCP power_out High-side gate-drive charge-pump storage pin, which requires a 0.01uF capacitor to VM.
12 VM power_in Motor supply pin, which requires filtering and at least 10uF to ground; the recommended supply range is 2.7V to 12V.
13 GND power_in Device ground; all ground pins and the exposed pad must be connected to system ground.
14 VINT power_out Internal regulator node, which requires a 2.2uF capacitor to ground.
15 AIN2 input H-bridge A input 2 logic input that controls AOUT2, with an internal pull-down.
16 AIN1 input H-bridge A input 1 logic input that controls AOUT1, with an internal pull-down.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
