PALC22V10-25PL Datasheet Connecting External LEDs to the EV Kit Surface-mount white LEDs come installed on the EV kit, but it can also be connected to an external LED string. To connect external LEDs, cut the trace shorting JU4. Then, connect the anode of the series string to OUTl+ and connect the cathode of the series string to OUTl-. PALC22V10-25PL Price Slow Current-Decay Mode. When VPFD > 3.5 V, the device is in slow current-decay mode (the source drivers are disabled when the load current reaches ITRIP). During the fixed offtime, the load inductance causes the current to recirculate through the motor winding, sink driver, ground clamp diode, and sense resistor (see figure l). Slow-decay mode produces low ripple current for a given fixed off time (see figure 2). Low ripple current is desirable because the average current in the motor winding is more nearly equal to the desired reference value, resulting in increased motor performance in microstepping applications. For a given level of ripple current, slow decay affords the lowest PWM frequency, which reduces heating in the motor and driver IC due to a corresponding decrease in hysteretic core losses and switching losses respectively. Slow decay also has the advantage that the PWM load current regulation can follow a more rapidly increasing reference before the PWM frequency drops into the audible range. For these reasons slow-decay mode is typically used as long as good current regulation can be maintained. PALC22V10-25PL on stock
