Application Circuits (Pin numbers are for an example of MMP-4P.)

1. Normal hard reset

Delay time (tPLH)

=··1.3Cd Rd+0.007 (mS)

Cd : µF Rd : kΩ

Note: Connect a capacitor between IC pins 1 and 2 if

VCC line impedance is high.

2. Manual reset added

Note: Use RL, CL and Rm to prevent manual switch

chattering. Connect a capacitor between IC

pins 1 and 2 if VCC line impedance is high.
