Analog/Digital Inputs
Pins J3-4 and J3-6 are analog/digital inputs. e analog signals have 12-bit resolution and also are
decoded as digital signals.
You can use parameters to specify the digital high and low thresholds. is allows you to connect
the inputs to analog sensors and congure the digital high- and low-level thresholds to indicate
conditions such as over/under pressure and high/low level points.
e following considerations apply to the analog/digital inputs:
• To specify the high and low thresholds of the analog/digital inputs, use the Digital/Analog
Input 1 and Digital/Analog Input 2 menus.
• You can use pin J3-4 as a generic analog/digital input if the vehicle system does not use an
emergency reverse NC switch and the EMR Input Type parameter is set to 0.
e following table describes the analog specications for the analog/digital inputs:
Specification Value
Measurement Range 0–19V (±10%)
Input Impedance > 5k
Time Constant < 1ms
Note: For the digital specications, see Digital Inputs.
Driver Outputs
e controller provides three low-side coil drivers. Each driver supports a continuous 1.5A load and
can be congured to operate in Direct PWM or Voltage Compensated PWM mode. e following
table describes the PWM modes:
Mode Description
Direct PWM The output voltage is not adjusted to account for uctuations
in battery voltage.
Voltage Compensated PWM The output voltage is adjusted to compensate for uctuations
in battery voltage, maintaining a near-constant average
voltage at the pin.
