PLD

It has a built-in CPLD and On-Chip Oscillator for configuring sequence control, and can programmatically create any power supply sequence. In addition, it has up to 6 Digital Inputs, and it is possible to incorporate arbitrary signals into the sequence.

Analog Input

Up to 12 channels of analog input are possible. A comparator for voltage monitoring is connected to each input port. By incorporating the comparator output into the sequence, it is possible to create a sequence based on the actual voltage and monitor voltage abnormalities during system operation. It can monitor from 0V to 5.75V, the comparator can be set up to 368 trip points, and the monitoring can be set with a high resolution of 15-20mV.

It also has two comparators per channel, enabling window monitoring (excluding POWER605/POWER607). It is also possible to support monitoring of voltages outside the specified range (including negative voltages) by installing an external circuit.

Open Drain Output

The output is 5V tolerant open drain. Sequence control is possible by inputting to the Enable Port of the DC/DC converter. In addition, it has up to 4 channels of 12V tolerant Open Drain output ports, and can also drive MOSFETs. (Except POWER605)

ADC

The POWER1220AT8/POWER1014A series has a 10-bit ADC and can read analog input values externally via the I2C interface.

TRIM Control

POWER1220AT8 has 8ch trim output port. By connecting to a DC/DC converter with a trim port, it is possible to stabilize the output voltage with an accuracy of ±1% or less. In Power Manager II [Pac-Power], monitoring voltage is read by ADC and fed back, so you can expect stable output under temperature and aging while using inexpensive DC/DC. In addition, since 4 sets of output values can be held per channel, it can be used for upper and lower limit inspections in shipping inspections.
