2ch DC Brush Motor Driver
BD60203EFV
General Description
BD60203EFV is 2ch H-bridge motor driver for DC brush
motor. This driver can facilitate low power consumption by
PWM constant current control. Various protection circuits
are built in. And also a circuit for lock detection is built in,
so it is possible to output an error detection signal
corresponding to Wired-Or signaling motor lock status. It
contributes to high reliability of the set.

Caution 1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is
operated over the absolute maximum ratings.
Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the
properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance taken into consideration by
increasing board size and copper area so as not to exceed the maximum junction temperature rating.
