HD151015
Application
For power management system (1)
V_CCA system
V_CCA
Be able to set up
variable power
supply voltage
from 2 V to 6 V
HD151015
V_CCB system
V_CCB
Be able to set up
variable power
supply voltage
from 2 V to 6 V
Be able to turn
on and off
Note:
HD151015 is also used for power management system. We show some Examples.
1. For V_CCA side
Be able to switch fast mode (V_CCA = 5 V) and power save mode (V_CCA = 3 V)
2. For V_CCB side
Be able to switch normal mode (V_CCB = 5 V) and suspend mode (V_CCB = 0 V)
3. For both side
Be able to switch fast mode (V_CCA = 5 V) and power save mode (V_CCA = 3 V)
(When V_CCA = V_CCB, in this case, please switch V_CCA and V_CCB simulteneously.)
For power management system (2) (Common bus line in different power system)
V_CCA system
HD151015
V_CCB system
V_CCB = 0 V
V_CCB
=0V

V_CCB' system
HD151015 uses conventional CMOS input circuit. So, you have to care of designing in case of common bus
line in different power block. We show one example.
In this case, if V_CCB become turn off, current flows from bus line to V_CCB. (refer to *¹)
This is cause of malfunction. In order to prevent this problem, I recommend using this device for interface to
each power block. (refer to *²)
[Cautions on using]
Please use this IC on condition of V_CCA usually ON, because if you use it on condition of V_CCA being OFF, V_CCB being
ON, it will be troubled.
