The EV6400DJ-00A is an evaluation board of MP6400. It is designed for voltage supervisory application with low quiescent current and programmable RESET delay time. The circuit monitors the sense voltage (Vsen) with Vcc from 1.8V to 6V. The MR (Manual Reset) function could introduce an external digital signal to control the RESET output. The RESET delay time could be programmed by the external capacitor.

The monitored voltage Vsen could be set from 0.4V through R1 and R2, and the delay time could be programmable from 2.1ms to 10s through C2. On the EV6400DJ-00A, the monitored voltage is set at 3.3V and RESET delay time at 100ms.
