RS806

Supply Voltage Supervisor with Watchdog and Manual

Reset

1 FEATURES

3 DESCRIPTIONS

The RS806 microprocessor (µP) supervisory circuits

reduce the complexity and number of components

required to monitor power-supply and battery function

in µP systems. This device significantly improves

system reliability and accuracy compared to separate

ICs or discrete components.

•

Operating Voltage Range:1.2V to 5.5V

Low Power Consumption:50µA (Max)

Precision Supply-Voltage Monitor:

2.63V, 2.93V, 3.08V, 4.00V, 4.65V

̅̅̅̅̅̅̅̅̅

•

Guaranteed 퐑퐄퐒퐄퐓 Valid at V_CC=1.2V

200ms Reset Pulse Width

Voltage Monitor for Power-Fail or Low-

Battery Warning

The RS806 provide four functions:

1) A reset output during power-up, power-down, and

brownout conditions. The reset output remains

operational with V_CCas low as 1.2V.

•

Operating Temperature Range:

-40°C to +125°C

̅̅̅̅̅̅̅̅̅

2) RESET output that goes low if the watchdog input

has not been toggled within 1.6 seconds (typ).

3) A 1.2V threshold detector for power-fail warning, low-

battery detection, or for monitoring a power supply.

4) An active-low manual-reset input.

Available in Green Package: SOT23-5

2 APPLICATIONS

The RS806 is available in Green SOT23-5 package. It

operates over an ambient temperature range of -40°C

to +125°C.
