Diodes – ZXBM5210 High Performance Single Phase Reversible DC Motor Drive with Speed Control

For system flexibility the device has forward, reverse, brake and standby modes of operations, selected by FWD and REV pins. The motor speed can be controlled linearly by PWM signal duty ratio on FWD and REV pins or alternatively by adjusting DC voltage input signal to the Vref pin.

The device has a wide supply voltage range of 3V to 18V with an operating ambient temperature range of -40oC to 105oC. To minimize power consumption, the ZXBM5210 quiescent current is 0.85mA with 32uA typical in standby mode.

In the motor industry, protection is critical. To help protect the motor coil, the device provides under voltage lockout, over voltage protection, over current limit and thermal shutdown and high ESD withstand capability. The ZXBM5210 is available in industry standard SO-8 thermally capable SO-8EP packages.

The Diodes Advantage:

The ZXBM5210 is a high performance solution for reversible DC motor drives with speed control for consumer, home appliances and industrial applications.

Four modes of operations: Forward, Reverse, Brake and Standby mode

  • High stable solutions providing system flexibility
