HX hengjiaxing · Supervisor And Reset ICs · SOT-89
HX7027A from HX hengjiaxing, in a SOT-89. 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 | OUT | output | Chip output terminal; the datasheet gives the output range as GND-0.3 V to VDD+0.3 V and an output sink current IOL of 0.5 mA to 1 mA at VDD = 2 V with VOUT = 0.2 V. |
| 2 | VDD | power_in | Chip supply input; the datasheet gives an operating voltage of 1.5 V to 12 V and an absolute maximum input voltage of 15 V. |
| 3 | GND | power_in | Chip ground terminal, which is the reference for the output voltage range (GND-0.3 V to VDD+0.3 V). |
