Electrical Characteristics (at T

= 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
