H7050A-1NPR
Shanghai Siproin Microelectronics · Supervisor And Reset ICs · SOT-89-3
H7050A-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 | Output that goes high-impedance when VDD exceeds VDET(+) and goes to VSS when VDD is at or below VDET(-); for H7050A-1 the sink current is 3 mA min (6 mA typ) at VDD = 2 V and VOUT = 0.2 V. |
| 2 | VIN | power_in | Supply voltage input with an operating voltage of 1.5 V to 16 V and an absolute maximum range of -0.3 V to 16 V. |
| 3 | GND | power_in | Ground connection. |
