ISL61851EIBZ-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 | GND | power_in | IC ground reference; all voltages are specified relative to GND. |
| 2 | VIN | power_in | Chip bias and UVLO input with a range of 0V to 5.5V; below VIN 1.7V the chip is disabled, FLT floats and OUT is held low. |
| 3 | EN1 | input | Enable input for switch 1 (active-high EN option for this ordering code), with an internal 1MΩ pull-off and a range of 0V to VIN. |
| 4 | EN2 | input | Enable input for switch 2 (active-high EN option for this ordering code), with an internal 1MΩ pull-off and a range of 0V to VIN. |
| 5 | FLT2 | output | Overcurrent fault indicator for switch 2 that floats until VIN exceeds VUVLO, is pulled low after the current-limit time-out, and has a range of 0V to VIN. |
| 6 | OUT2 | power_out | Controlled supply output for switch 2 that is current limited on overcurrent (response within 200µs) and turns off after a nominal 12ms in current limit, with a range of 0V to VIN. |
| 7 | OUT1 | power_out | Controlled supply output for switch 1 that is current limited on overcurrent (response within 200µs) and turns off after a nominal 12ms in current limit, with a range of 0V to VIN. |
| 8 | FLT1 | output | Overcurrent fault indicator for switch 1 that floats until VIN exceeds VUVLO, is pulled low after the current-limit time-out, and has a range of 0V to VIN. |
