SD540B Performance Characteristics

PWM Signal Linearity:

Note the 4 milliseconds dead-band in the center (at 1500ms), i.e. motors won't move between pulse 1498 ms to 1502ms

Stall characteristics

In this test, a running motor was stalled mechanically for about 5 minutes.

During this test probes were connected to SD540B to measure various properties, the chart above shows graph of measured temperature.
