Description
The ZXBM5210 is a highly integrated high performance single chip solution for reversible brushed direct current (DC) motors and actuators.
For system flexibility the device has four modes of operation: forward, reverse, brake and standby modes. The operating mode and direction of rotation can be slectedcan by the FWD and REV pins. Additionally, the motor speed can be controlled linearly by changing the duty ratio of the PWM signal on the FWD or REV pins in the PWM mode or alternatively by adjusting the DC voltage input signal to the VREF pin in the Vref mode. The device has a wide supply voltage range of 3V to 18V and the operating ambient temperature range of -40°C to +105°C.
To help protect the IC and the motor coil the ZXBM5210 includes under voltage lockout, over voltage , over current and over thermal shutdown protection functions. Once the safe operating range has been exceeded the device shuts down the output drive to help prevent over stress on the IC or the coil. The device internal current protection threshold is 1.5A typical at 12V. To aid power efficiency the ZXBM5210 has a standby mode, consuming 32µA typical. Product reliability and robustness is further enhanced by the devices’ high ESD withstand capability of 6kV and extended operatign temperature ranges.
The ZXBM5210 is available in the standard SO-8 and thermally enhanced SO-8EP packages.
