DESCRIPTION

M61018GP is a semiconductor integrated circuit built-in motor driver for compact camera. All power transistors which have been used as external parts so far are built in by using minute bi-polar process ,so it contributes to reduction of the part cost and the miniaturization of the system .

FEATURES

• Built-in DC/DC converter (Presser type,TYP 5.0V)

• Built-in Regulator circuit for Auto Focus (Depressor type,TYP 4.1V)

• Built-in IRED drive circuit (TYP Io=1A)

• Built-in DC motor driver circuit of 1.5CH

APPLICATION

Motor driver for compact camera etc.
