AKM releases power control IC, the AP1400, which supports 2-cell Li-ion batteries with flexible power supply sequence control.
2017-05-19 | ReturnAP1400AEC
Product Category:
Power Management > Power Control IC > Power Management IC (PMIC)
Features
Support 4 to 12 V Input Voltage
Multichannel System Power Control IC
Sequencial Control by Registers
Various Protection Functions
Applications
Digital Single-lens Reflex Cameras, Mirror-less Cameras, Camcorders
Description
Asahi Kasei Microdevice Corporation, (AKM), has launched a multi-channel power control IC, the AP1400, 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 AP1400 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.
● Flexible Control of Power Up Sequence
Since the wait time until start-up operation (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.
● Low Standby Current
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.
● Small Package
The AP1400 is housed in a small WLCSP of 2.9 mm x 4.1 mm, shrinking the system size.
