GENERAL DESCRIPTION
The ADM6316-ADM6322 are supervisory circuits which
monitor power supply voltage levels and code execution
integrity in microprocessor-based systems. As well as providing
power on reset signals, an on-chip watchdog timer can reset the
microprocessor if it fails to strobe within a preset timeout
period. A reset signal can also be asserted by means of an
external push-button, through a manual reset input. The seven
parts feature different combinations of watchdog input, manual
reset input and output stage configuration, as shown in table 1.
Each part is available in a choice of 26 reset threshold options
ranging from 2.5V to 5V in 100mV increments. There are also 4
reset timeout options of 1ms, 20ms, 140ms and 1120ms (min)
and 4 watchdog timeout options of 6.3ms 102ms, 1600ms and
25.6s (typ).
The ADM6316-ADM6322 are available in 5-lead SOT-23
packages and typically consume only 3µA, making them
suitable for use in low power portable applications.
