AM4961GHTR-G1 from Diodes Incorporated, in a HTSSOP-14. 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 | OUT2 | output | Driver output 2; output saturation is 1.17 V max at 200 mA source and 0.3 V max at 200 mA sink, with output current rated 1.0 A absolute maximum. |
| 2 | VCC | power_in | Power supply, 3.5 V to 16 V recommended (12 V typ) with 18 V absolute maximum; a capacitor of no less than 1 µF is employed to stabilize VCC. |
| 3 | VMIN | input | Minimum duty setting input; if unused, connect it directly to VPWM, which sets the minimum duty cycle to 10%. |
| 4 | VPWM | input | Adjustable PWM speed-control input with a 6 V absolute maximum input voltage. |
| 5 | COSC | passive | Oscillator capacitor terminal; with COSC = 100 pF the oscillator frequency is 25 kHz typical (18 kHz to 32 kHz). |
| 6 | FG | output | Rotation speed indicator, open-collector output with 0.3 V max low level at 5 mA and 30 µA max leakage at VFG = 12 V. |
| 7 | RD | output | Rotation or lock state indicator, open-collector output that is low in rotation mode and high when stopped, with 0.3 V max low level at 5 mA and 18 V absolute maximum output voltage. |
| 8 | HIN+ | input | Hall sensor input +, with a 0.2 V to 3 V input voltage range (including signal amplitude) and ±10 mV to ±20 mV hysteresis. |
| 9 | HB | power_out | Hall sensor bias regulator output providing 1.25 V typical (1.1 V to 1.4 V at 5 mA), with 10 mA absolute maximum output current. |
| 10 | HIN- | input | Hall sensor input -, with a 0.2 V to 3 V input voltage range (including signal amplitude) and ±10 mV to ±20 mV hysteresis. |
| 11 | VREF | power_out | Reference voltage regulator output providing 6 V typical (5.8 V to 6.2 V at 5 mA). |
| 12 | CT | passive | Lock and rotation setting capacitor terminal; CT swings between 1.7 V (typ low) and 3.7 V (typ high) with 2 µA typical charge and 0.2 µA typical discharge current. |
| 13 | GND | power_in | Ground for the control circuit; all control-stage ground lines are connected to GND. |
| 14 | OUT1 | output | Driver output 1; output saturation is 1.17 V max at 200 mA source and 0.3 V max at 200 mA sink, with output current rated 1.0 A absolute maximum. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
