<REGCNT pin control – set up method>
(1) REGCNT Pin Control setup (excluding LDO1)
(2) Control using the I
OPERATION ( Continued )
3. Register map details
Note) The characteristics listed below are reference values derived from the design of the IC and are not guaranteed.
1) Select the LDO/DCDC to be controlled by REGCNT
2) Set the LDO/DCDC Startup register mentioned above in ① to “H”
3) LDO/DCDC selected in 1) above will startup when REGCNT is set to “H”
4) The Startup for LDO/DCDC not selected in 1) can also be controlled by the I
5) To turn off the LDO mentioned in 1) above, set the REGCNT to “L”.
1) ADDRESS 04h：DATA 61h
2) ADDRESS 00h：DATA 18h
3) Set REGCNT pin “L” to “H” : LDO2,3 Startup
4) Use I
5) To stop LDO2 and LDO3, Set REGCNT from “H” to “L”
Initial setup
Startup Control
Example Using the REGCNT pin to control LDO2 and LDO3
Initial Setup
(Startup control)
(Address:04h Single Bit from D7-5, D3 should be set to “H”)
Set D0 to “H”
(To control LDO1 set Address:00h D2:LDO1ON to “H”)
Power Save Mode for the LDO can be controlled by the I
When the Startup register mentioned in 2) above (Address:00h) is set to “L”, the LDO/DCDC will turn off.
When the LDO is turned OFF in the Power Save Mode, reset Address:05h to Normal Mode before turning on
the LDO using the REGCNT pin.
No special settings required after RESET
(ADDRESS 04h Bit D0 set to “L)
The REGCNT pin should be set to “L” when using the I
and Output Voltage Setup.
Set the LDO to be controlled to Normal Mode (Address:05h Default)
