DESCRIPTION
The DS1836 MicroManager performs three vital system functions.First, a precision temperaturecompensated reference and comparator circuit monitor the status of the voltage on VCC and when an outof-tolerance condition is detected, an internal power-fail signal is generated that forces the reset
Features
- 5V or 3.3V power-on reset.
 
- True 3V operation power switch.
 
- Switches to battery at 3.8V (2.6V for 3.3V
versions).
 
- Excellent for systems designed to operate
with dual power supplies.
 
- Asserts resets during power transients.
 
- Maintains reset for 350ms after VCC returns to
an in-tolerance condition.
 
- Reduces need for discrete components.
 
- Precision temperature-compensated voltage
reference and voltage sensor.
 
- 8-pin DIP or space saving 8-pin SO surface
mount.
