The ADM1067 is a super sequencer with open-loop margining DACs, which provides high-precision power supply monitoring and power switch control.
The ADM1067 Super Sequencer is a configurable supervisory and sequencing device that monitors up to 10 supplies and provides 10 programmable driver outputs. It integrates six 8‑bit voltage‑output DACs for open‑loop margining and includes a sequencing engine capable of up to 63 states.
The datasheet provides detailed specifications such as supply voltage ranges, input impedance, current consumption, and absolute maximum ratings, as well as pin configurations, timing parameters for the SMBus interface, and ordering information for the 40‑lead LFCSP and 48‑lead TQFP packages.
| Supply Voltage Range (VH) | 3.0 V to 14.4 V |
|---|---|
| Supply Voltage Range (VPx) | 3.0 V to 6.0 V |
| Supply Current (typical) | 42 µA |
| DAC Resolution | 8 bits |
| Input Impedance (VH Pin) | 52 kΩ |
The VH pin has an input impedance of 52 kΩ.
The device provides ten programmable driver outputs (PDO1 to PDO10).
Each of the six DACs has an 8‑bit resolution.
The VH pin can tolerate up to 16 V absolute maximum rating.
