HTD9801TSH

Jiaxing Heroic Elec Tech · Stepper Motor Driver · TSSOP-16

HTD9801TSH from Jiaxing Heroic Elec Tech, in a TSSOP-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, low puts the device into low-power sleep; internal 1000 kΩ pull-down to GND and 5.8 V zener clamp, so a pull-up to VM should use 10 kΩ to 100 kΩ.
2 AOUT1 output H-bridge A output 1, connected to motor winding A.
3 AISEN passive H-bridge A current-sense pin: connect the sense resistor to GND, or tie directly to GND if current regulation is not used; trip threshold VTRIP is 180 mV to 260 mV (220 mV typical).
4 AOUT2 output H-bridge A output 2, connected to motor winding A.
5 BOUT2 output H-bridge B output 2, connected to motor winding B.
6 BISEN passive H-bridge B current-sense pin: connect the sense resistor to GND, or tie directly to GND if current regulation is not used; trip threshold VTRIP is 180 mV to 260 mV (220 mV typical).
7 BOUT1 output H-bridge B output 1, connected to motor winding B.
8 nFAULT output Fault output: goes low on over-temperature or overcurrent; open-drain, requires an external pull-up.
9 BIN1 input H-bridge B logic input 1, controls BOUT1; internal pull-down (about 100 kΩ typical).
10 BIN2 input H-bridge B logic input 2, controls BOUT2; internal pull-down (about 100 kΩ typical).
11 NC unconnected No internal connection; datasheet recommends leaving it floating or connecting it to ground.
12 VM power_in Motor supply, 2.0 V to 5.5 V recommended (absolute maximum 6.5 V); decouple with at least 10 µF to GND placed as close to the device as possible.
13 GND power_in Device ground; all ground pins and the exposed pad must be connected to system ground.
14 MODE input Operating-mode select: tri-state input (default NC) that selects 4-pin, 2-pin, or independent half-bridge input modes.
15 AIN2 input H-bridge A logic input 2, controls AOUT2; internal pull-down (about 100 kΩ typical).
16 AIN1 input H-bridge A logic input 1, controls AOUT1; internal pull-down (about 100 kΩ typical).
