AH1892-Z-7 from Diodes Incorporated, in a SOT-553-5. 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 | VDD | power_in | Power supply input, operating from 1.6 V to 3.6 V per the recommended operating conditions. |
| 2 | NC | unconnected | No connection, not connected internally; it can be left open or connected to ground. |
| 3 | BSEL | input | Band select input: tied low selects the low band, tied to VDD or above 1.4 V or left open selects the high band, with an internal 50 kΩ pull-up active only during the awake period. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | OUTPUT | output | Output is pulled low when B exceeds Bop and held until B falls below Brp, with VOL of 0.2 V max at IOUT = 1 mA and output current limited to 2.5 mA (source and sink). |
