Electrical Characteristics (at Tamb = 25°C & Vcc = 12V)

Notes:

1

Measured with pins H+, H-, CLCK and CPWM = 0V and all other signal pins open circuit.

2

The 1V minimum represents 100% PWM drive and 2V represents 0% PWM drive.

3

This voltage is determined by an internal resistor network of 52.5k

from the pin to Gnd and 19.5k

from the pin to a 2V reference. Whilst both

resistors track each other the absolute values are subject to a

20% manufacturing tolerance.
