See Graph F Operating Temperature Range, TA .................................. -20°C to +85°C D — Storage Temperature Range, 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. Active-low ENABLE inputs control the four drivers in each bridge. The bridges include both ground clamp and flyback diodes for protection against inductive transients.
