www.DataSheet4U.com M50224FP 1.5 Channel Motor Driver·with DC/DC Control REJ03F0070-0100Z Rev.1.0 Sep.19.2003 Description M50224FP is the semiconductor integrated circuit which builds in the Motor drive circuit and DC/DC circuit suitable for the camera etc. 1.5 H bridges, the DC/DC circuit of 5VDC/DC, and AE operation circuit were built in one tip by adoption of a detailed CMOS process. The reduction in power consumption and the miniaturization are considered as the high composition of the flexibility realized with one chip. Features Minute CMOS process acceptance.Low consumption 1.5 full swing voltage drive H Bridge circuit built-in (PWM drive correspondence) DC/DC circuit built-in of 5V One AE operation circuit built-in AE (A sensor corresponds to amorphous and SPD) Low voltage incorrect operation prevention circuit thermole shutdown circuit built-in A thermometer, with a power save function Application motor driver for cameras etc Recommend Operating Condition Supply voltage range........
