The APX6219 is designed to drive both winding of a two-phase bipolar stepper motor or bidirectionally control 2 DC motors. APX6219 includes two Hbridges capable of continuous output current of 750 mA with peak start up to 1A and operating voltages up to 28V. Motor winding current can be controlled by the internal fixed-frequency, pulse-width modulated (PWM), current-control circuitry. Wide range current control is controlled by means of two logic inputs with a external reference voltage for each bridge. The peak load current limit is set by the user's selection of a reference voltage and current-sensing resistor. Two logic-level select output current limits of 0%,33%, 67%, or 100% of the maximum level. A phase input to each bridge determines load current direction. A thermal shutdown protection circuit disables the outputs if the chip temperature over the safe operation limit. The APX6219 come in SOP-24 package. |
