HT7660ARZ from HTCSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No Connection |
| 2 | CAP+ | passive | Pump capacitor (C1) positive terminal; connect positive lead of 10μF capacitor for charge pump operation |
| 3 | GND | power_in | Ground reference |
| 4 | CAP-V | passive | Output filter capacitor (C2) positive terminal; connect positive lead of 10μF capacitor for output voltage filtering and ripple reduction |
| 5 | OUT | output | Negative voltage output with typical source resistance of 100Ω at 20mA load current, maximum 120Ω from 0°C to 70°C |
| 6 | LV | input | Low voltage mode control input; tie to GND for V+ <3.5V, leave floating for V+ >3.5V to prevent latchup; input voltage range -0.3V to (V+ +0.3V) |
| 7 | OSC | input | Oscillator frequency control input; nominal frequency 10kHz at V+ =5V, externally adjustable via external capacitor or external clock with 1kΩ series resistor |
| 8 | V+ | power_in | Positive supply voltage input with operating range 1.5V to 12.0V for HT7660A variant, absolute maximum rating 13.0V |
