ICL7660SCBAZ-T
RENESAS · Charge Pumps · SOIC-8
ICL7660SCBAZ-T from RENESAS, in a SOIC-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 | BOOST | input | Connecting the Boost Pin (Pin 1) to V+ increases the oscillator charge and discharge current and raises the oscillator frequency by approximately 3.5 times. |
| 2 | CAP+ | passive | Pump capacitor C1 connection; when polarized capacitors are used, the + terminal of C1 must be connected to pin 2. |
| 3 | GND | power_in | Ground reference; the output (pin 5) must not be taken more positive than GND (pin 3) or the device will latch up. |
| 4 | CAP- | passive | Pump capacitor return and reservoir-side node; an external Schottky diode from VOUT to CAP- may be needed to prevent latch-up when VIN is above 5V with a fast input rise rate. |
| 5 | VOUT | output | Negative converter output, VOUT = -VIN, which must not be pulled more positive than GND (pin 3) to avoid latch-up. |
| 6 | LV | input | Tie to GND to bypass the internal series regulator for low-voltage operation (1.5V to 3.5V supply), and leave floating for supplies above 3.5V to prevent latch-up. |
| 7 | OSC | input | Oscillator terminal where an external capacitor lowers the nominal 10kHz oscillator frequency, or where an external clock may overdrive the oscillator. |
| 8 | V+ | power_in | Positive supply input; high-range operation is 3.0V to 12V with LV open and absolute maximum supply is +13.0V. |
