ON Semiconductor | MAX810TTRG

The reset output is driven active within 10 µsec of VCC falling through the reset voltage threshold. Reset is maintained active for a timeout period which is trimmed by the factory after VCC rises above the reset threshold. The MAX810 has an active−high RESET output while the MAX809 has an active−low RESET output. Both devices are available in SOT−23 and SC−70 packages. The MAX809/810 are optimized to reject fast transient glitches on the VCC line. Low supply current of 0.5 µA (VCC = 3.2 V) makes these devices suitable for battery powered applications.
