Multi-channel power control IC equipped with a 4-channel DC-DC converter and a 2-channel LDO
The AP1400AEC is a multi-channel power control IC equipped with a 4-channel DC-DC converter and a 2-channel LDO, supporting 4 to 12 V input voltage.
Start and stop sequences for each channel can be set independently via registers. This enables a wide range of power control for the AP1400AEC according to each operation mode.
Since various protect functions such as input current sense function are built in, the AP1400 can be safely stopped in cases of abnormality.
Since the wait time until start-up oepration (0 to 32 ms, 8 settings), soft start time, (1 to 10 ms, 4 settings), and power-on channels can be selected via register settings, an optimum power profile for your product model and operation modes can be achieved.
In standby mode, the CPU power supply and I2C control are active. The current consumption as low as 19uA at maximum which provides a long battery life.
The AP1400 is housed in a small WLCSP of 2.9 mm x 4.1 mm, shrinking the system size.
