TMI88221 TMI88221B 20V Low Saturation Voltage Stepper Motor Driver with Built-in Micro-step Control Algorithm
●The TMI88221/B devices are the stepper motor drivers for TV camera, IPC, industrial equipment, and other low noise stepper motor application. With wide 4V to 20V input voltage range, TMI88221/B can be powered by DC power supply and single or multi-cell lithium battery.
●Different from traditional chips, there is no pulse width modulated (PWM) signals needed to drive stepper motors, which means only two logic signals are able to switch all the modes, and the built-in micro step algorithm in TMI88221/B can help to decrease the common noise and jittering of motor. Moreover, the TMI88221/B preset 3-level speed mode and can be adjusted easily. The TMI88221/B preset the low-power sleep mode, and the power consumption is narrowly closed to zero at this mode.
●The TMI88221/B can drive motors with up to 1A current. ESOP8 package is adopted.
