HX809T-3.08V

HX hengjiaxing · Supervisor And Reset ICs · SOT-23

HX809T-3.08V from HX hengjiaxing, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Chip ground reference (芯片接地端). Connect to system ground.
2 RESET output Active-low reset output (复位输出端). Asserted low when VCC falls below the 3.08 V threshold and held asserted for Trp (typ. 350 ms) after VCC returns above threshold. Absolute-max VRESET is -0.3 V to VCC+0.3 V; IRESET absolute-max 20 mA; VOL ≤ 0.3 V at ISINK=1.2 mA; VOH ≥ 0.8·VCC at ISOURCE=500 µA (T-suffix).
3 VCC power_in Chip supply / monitored input (芯片输入端). Operating range 0.9-6.0 V, absolute-max 6 V. This is the voltage the supervisor monitors against the 3.08 V reset threshold. Typical ICC = 2 µA at VCC = 5.5 V.
