MAX6866UK16D3S+T

The MAX6866UK16D3S+T is a nanopower microprocessor (μP) supervisory circuit with manual reset input and watchdog timer in 5 pin SOT-23 package. This microprocessor (μP) supervisory circuit combines voltage monitoring, watchdog timer and manual reset input functions. The device asserts a reset signal whenever the monitored voltage drops below factory trimmed reset threshold voltage, manual reset is asserted or watchdog timer expires. The reset output remains asserted for a minimum timeout period after VCC rises above the reset threshold and manual reset is deasserted. The watchdog timer monitors activity at the WDI input to prevent code execution errors.

• Supply voltage range from 1.2V to 5.5V
• Operating temperature range from -40°C to 85°C
• Active-low, open-drain reset output
• Ultra low supply current of 170nA at VCC = 1.8V
• Immune to short VCC transients
• Reset valid to VCC = +1.1V
• No external components are required
• Threshold voltage of 1.575V and reset timeout period of 225ms
• Watchdog timeout period is 3.3s
