DESCRIPTION

The µ PD168103A is the motor driver IC with IRIS control circuit, operational amplifier and 4-ch H-bridge output. Smooth operation is possible for IRIS control with linear method.

The package is 48-pin thin type QFN and then it helps reduce the mounting area and height.

The µ PD168103A is suitable for the lens drive of a camcorder, DSC, etc.

FEATURES

• PWM output (ch1 to ch4)

• Output current

DC current: ±0.3 A/ch (when each channel is used independently)

Peak current: ±0.7 A/ch (when each channel is used independently)

• 3-ch general-purpose operational amplifier

Input offset voltage: ±5 mV

Input voltage range: 0 to AVDD − 1.5 V

Output voltage range: 0.2 to AVDD − 0.2 V
