S1F81150 Series

System Power Suplly IC

DESCRIPTIONS

The S1F81150 is a System Power Supply IC. From the Li-Ion/Li-polymer battery, 6 channels of output voltage

are generated via external devices. The 6 channels are independent of each other.

On this series, an I²C controller (for the slave function), input and output voltage detecting functions and many

kinds of operation modes (Normal, Sleep, Deep Sleep, Ultra-Energy-Saving) are provided as well as three PWM

controller channels and three series regulator channel.

FEATURES

The features of the S1F81150 include the following:

Input voltage:

Regulator:

V_IN

6 channels

3.3V to 5.5V

CH-1 (V_CC1): PWM controller

Fast synchronized rectification type PWM controller

(Connected to an external component to configure a switching regulator.)

Features include a fast response circuit using a current/voltage returning system, a short-circuit-proof

circuit, a soft-start system, more compact external components by a fast clock, and dynamic voltage

management system.

Output voltage:

0.80~1.55 V (0.05V step variable)

One of these values is to be selected via the I²C controller.

Accuracy:within +/- 5%

Output current:

In the sleep status: Off.

In the normal operation:

Max: 500mA

CH-2 (V_CC2): PWM controller

Fast synchronized rectification type PWM controller

(Connected to an external component to configure a switching regulator.)

Features include a fast response circuit using a current/voltage returning system, a short-circuit-proof

circuit, a soft-start system and more compact external components by a fast clock.

Output voltage:

3.3 V

Accuracy:within +/- 5%

In the deep sleep status:

In the backup operation:

In the normal operation:

Output current:

Off.

Max:10mA

Max: 1A
