5V Reset Controller
The EMC2102 also provides a ‘power-good’ reset controller for the system’s 5V supply rail. The reset
controller will set the RESET# pin to a logic ‘0’ after power-up and set the RESET# pin to a logic ‘1’
220ms after the VDD_5V supply rises above its threshold voltage (see
Table 3.2, "Electrical
Specifications").
If the VDD_5V supply drops below the reset threshold, then the RESET# pin will be set to ‘0’
immediately.
