Enter Power Down Mode
Microcomputer issues power down command to M61047FP after microcomputer detects that battery voltage is too
low. After this command, the DFET pin is set to 'high' and the VIN12 pin is pulled down by internal resistor to be
set 'low' and series regulator are turned off.
In the power down mode, the M61047FP operation is impossible. And CFET, DFET and PCFET are set to 'high'.
(In this situation, discharging is forbidden.) At this time, supply current becomes max. 0.5
μ
A, so drops of battery
voltage is prevented.
Resume from Power Down Mode
After entering Power Down mode, the series regulator will begin operation when charger is connected (VIN12 pin is
high). The RESET will output low to high signal when Vreg is over reset level voltage. Microcomputer will begin
operation and send command to resume M61047FP from power down mode.
