H7070A-1NPR
Shanghai Siproin Microelectronics · Supervisor And Reset ICs · SOT-89-3
H7070A-1NPR from Shanghai Siproin Microelectronics, in a SOT-89-3. 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 | VOUT | output | NMOS open-drain detector output that is Hi-Z when VDD > VDET(+) and pulled to VSS when VDD ≤ VDET(-), with a minimum 3 mA sink current at VOUT=0.2V and VDD=2V for the 7.0V version. |
| 2 | VIN | power_in | Supply and voltage-sense input with an operating voltage of 1.5V to 16V and an absolute maximum of -0.3V to 16V. |
| 3 | GND | power_in | Ground (VSS) reference pin for the device. |
