The AM2170 motor driver is designed to drive both windings of a bipolar stepper motor or to control bi-directionally two DC motors. Both bridges are capable of sustaining 45V and include internal pulse-width modulation (PWM) control of the output current to 750mA. The outputs have been optimized for a low output saturation voltage drop (less than 1.8V total source plus sink at 500mA).\r\n For PWM current control, the maximum output current is determined by the user’s selection of a reference voltage and sensing resistor. Two logic-level inputs select output current limits of 0, 33%, 67%, or 100% of the maximum level. A PHASE input to each bridge determines load current direction.\r\n The bridges include both ground clamp and fly-back diodes for protection against inductive transients. Internally generated delays prevent cross-over currents when switching current direction. Special power-up sequencing is not required. A thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits.\r\n The IC is supplied in HSOP28 Package. Its thermal wing construction provides for maximum package power dissipation in the smallest possible construction. Package material is Pb-Free for purpose of environmental protection.
