HT8691Q5SPER from Jiaxing Heroic Elec Tech, 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 | FB | input | Regulator feedback input; boost output set by PVDD = 1.24*(Rd1+Rd2)/Rd2 from a resistive divider. |
| 2 | LX | input | Internal boost switch node; an RC circuit from LX to ground is strongly recommended to reduce ripple current. |
| 3 | PVDD | power_in | Boost converter output voltage and power supply; recommended 6.5V to 7.5V, absolute maximum 7.8V. |
| 4 | OUT- | output | Negative speaker output terminal (BTL-). |
| 5 | OUT+ | output | Positive speaker output terminal (BTL+). |
| 6 | IN+ | input | Positive differential audio input via DC-cut capacitor; source output impedance should be 600 ohm or lower. |
| 7 | IN- | input | Negative differential audio input via DC-cut capacitor; source output impedance should be 600 ohm or lower. |
| 8 | CTRL | input | Shutdown and ACF mode control; voltage thresholds select Class D ACF-off, ACF-on, Class AB or shutdown, with 120k internal pull-down in Class D. |
| 9 | GND | power_in | Power ground (exposed thermal pad). |
