It is a high-accuracy, low current consumption Voltage Detector IC series with a built-in delay circuit.
The lineup was established with two output types (Nch open drain and CMOS output) and detection voltages range from 0.
9V to 4.
8V in increments of 0.
1V, so that the series may be selected according to application.
●Features „ Delay Time Controlled by external Capacitor „ Two output types (Nch open drain and CMOS output) „ Ultra-low current consumption „ Wide operating temperature range „ Very small and low height package „ Package SSOP5 and SOP4 is similar to SOT-23-5 and SC-82 respectively (JEDEC) ●Typical Application Circuit VDD1 RL BU42xx CIN CT CL (Capacitor for noise filtering) ●Applications Circuits using microcontrollers or logic circuits that require a reset.
