Description

The S-7750B is a programmable port controller IC comprising E2PROM, a data output controller, a circuit to prevent malfunction during low supply voltage, etc.

It operates at 400 kHz and interfaces with external devices via the I2CBUS. High and low of the 8-channel digital output, and the delay time of each channel can be controlled by serial signals.

Initial value, and reverse delay time can be set for the 8-channel digital output pins, respectively for each port. This is effective for controlling turning on or off the voltage regulator in mobile phones.

The built-in E2PROM allows the initial value of each control settingto be retained when power is off.
