The TCM809 and TCM810 are low‑power 3‑pin reset monitor ICs that supervise Vpp in digital systems and provide a reset signal to the host processor when the supply voltage falls below a threshold. They operate without external components and are offered in SC‑70 and SOT‑23B packages.
Key specifications include a minimum 140 ms reset timeout, a typical supply current of 9 pA, and operation over a temperature range from –40 °C to +125 °C. The devices support multiple Vpp levels (+2.5 V to +5 V) and provide push‑pull reset outputs (active‑low for TCM809, active‑high for TCM810).
| Minimum Reset Timeout | 140 ms |
|---|---|
| Low Supply Current (typ.) | 9 pA |
| Supply Voltage Range (Vpp) | +2.5 V to +5 V |
| Package Types | 3‑Pin SC‑70, SOT‑23B |
| RESET Output Valid Down To | Vpp = 1.0 V |
The device guarantees a minimum reset timeout of 140 ms.
The RESET output remains active for at least 140 ms (typically up to 240 ms) after Vpp exceeds the threshold.
Typical supply current is 9 pA.
Both devices are offered in 3‑Pin SC‑70 and SOT‑23B packages.
