BIPOLAR Power Voltage Monitoring IC with Watchdog Timer MB3793-37A sDESCRIPTION
A reset signal is output when the power is cut or falls abruptly. An internal watchdog timer with two inputs for system operation diagnosis can provide a fall-safe function for various application systems. There is also a mask option that can detect voltages of 4.9 to 2.4 V in 0.1-V steps. The model number is MB3793-37A corresponding to the detected voltage. The model number and package code DataShee are as shown below. Model No. Package code Detection voltage DataSheet4U.com MB3793-37A 3793AF 3.7 V sFEATURES
