Watchdog Output. WDO pulses low for the watchdog output B1 4 B1 4 WDO pulse width, tWDO, when the internal watchdog times out. WDO is an open-drain output and requires a pull-up resistor. Manual Reset Input. Drive MR low to manually reset the device. RST remains asserted for the reset timeout period after MR is B2 5 — — MR released. MR is internally pulled up to VCC with a 100kΩ resistor. Watchdog Enable Input. Drive WD_EN high to enable the — — B2 5 WD_EN watchdog timer. Drive WD_EN low to disable the watchdog timer. Reset Output. RST asserts when VCC falls below the factory-set threshold. When VCC goes above VTH+ VHYS, RST remains B3 6 B3 6 RST asserted for the reset timeout period tRP and then de- asserts. RST is an open-drain output and requires a pull up resistor. www.maximintegrated.com Maxim Integrated | 9 Document Outline General Description Applications Benefits and Features Typical Application Circuit Absolute Maximum Ratings Package Information Electrical Characteristics Pin Configurations 6 WLP 6 SOT23 6 WLP 6 SOT23 Pin Description Functional Diagrams MAX16152/MAX16153 Block Diagram MAX16154/MAX16155 Block Diagram Detailed Description Input Threshold Watchdog Watchdog Startup Delay Watchdog Timeout Period Watchdog Enable Input (WD_EN) Watchdog Input Signal Reset Timeout Period Manual Reset Applications Information Power Supply Bypassing Watchdog Software Considerations Negative-Going VCC Transients Protection Selector Guide Ordering Information Revision History
