This is an application note about voltage monitoring and sequencing. It introduces the new ADM6326, ADM6328, ADM6346 and ADM6348 ultralow power microprocessor supervisory circuits, which are suitable for monitoring power supplies in portable microprocessor-based applications and extend battery life.
Analog Devices introduces a new family of ultralow power supervisory circuits suited to monitoring power supplies in portable microprocessor-based applications. These devices extend battery life by consuming only 500 nA (typ) supply current while maximizing reliability through robust power supply monitoring.
The document details the specifications for the ADM6326, ADM6328, ADM6346, and ADM6348 models. Key features include reset thresholds available from 2.2 V to 4.63 V, a minimum 100 ms power-on reset pulse width, and availability in a 3-lead SOT-23 package requiring no external components. Three versions are offered: push-pull active low, push-pull active high, and open-drain active low.
| Supply Current | 500 nA (typ) |
|---|---|
| Reset Threshold Range | 2.2 V to 4.63 V |
| Power-On Reset Pulse Width | 100 ms (min) |
| Package Type | 3-lead SOT-23 |
The supply current is 500 nA typical.
They use a 3-lead SOT-23 package.
