Monolithic IC MM3018
Outline
This is a reset + regulator composite IC developed using the
CMOS process. The
CMOS process is used to achieve ultra-low current consumption, aiming at use in memory cards and portable devices. Further, this exceptional IC can be used even when board mounting space is limited, due to the wafer level package, WLCSP-6.
Features
1. Built-in thermal shutdown circuit 2. Built-in current limit circuit 3. Low current consumption 15µA typ. 4. Series with reset detection
voltage in 0.1V steps 5. Delay time from
voltage detection to reset release can be set easily.
Package
WLCSP-6
Applications
1. Microcomputer, CPU and MPU reset circuit 2. Logic circuit reset circuit 3. Battery
voltage check 4. Back-up circuit switching circuit 5. Level detection circuit 6. Mechanical system reset circuit
