MAX809

Very Low Supply Current

3-Pin Microprocessor

Reset Monitors

The MAX809 is a cost–effective system supervisor circuit designed

to monitor V_CCin digital systems and provide a reset signal to the host

processor when necessary. No external components are required.

The reset output is driven active within 10 µsec of V_CCfalling

through the reset voltage threshold. Reset is maintained active for a

minimum of 140 msec after V_CCrises above the reset threshold. The

MAX809 has an active–low RESET output. The output of the

MAX809 is guaranteed valid down to V_CC= 1.0 V. This device is

available in a SOT–23 package.

(TO–236)

CASE 318

xxxM

The MAX809 is optimized to reject fast transient glitches on the V_CC

line. Low supply current of 1.0 µA (V_CC= 3.2 V) make this device

suitable for battery powered applications.
