DESCRIPTION
The EM6323/24 are low power, high precision reset ICs featuring a manual reset and a watchdog inputs. They have different threshold voltages and several timeout reset periods (tPOR) and watchdog timeout periods (tWD) for maximum flexibility in the application. EM6323 has a manual reset ( MR with internal pull-up) and a watchdog input pins. EM6324 has only a watchdog input pin (WDI). The watchdog function can be disabled by driving WDI with a three-state driver or by leaving WDI unconnected. This is useful when the MCU is in sleep mode. Small SOT23-5L package as well as ultra-low supply current of 3.8μA make the EM6323 and Typical Application VDD GND VDD RESET RESET EM632x MR WDI GND * VDD RESET RESET MPU, DSP I/O GND * REXT for open-drain version only Fig. 1FEATURES
