20 CM2115
Inputs
The following table provides specifications for the CM2115's power control
digital input:
Power Control Digital Input Specifications
Item MIN NOM MAX UNIT
Input voltage range 0 - 32 V
Over-voltage - - 36 V
Inductive load protection - Yes - -
Pull-down resistance 1.9 2.0 2.1 k Ω
Capacitance at pin - 0.01 - µF
Negative going input threshold - - 1.56 V
Positive going input threshold 3.82 - - V
Input Power Up Threshold 1.4 - 3.9 V
Cutoff frequency (hardware) - 98 - Hz
Note:
The power control digital input voltage must be greater than 3.9 V
before it is considered an active high input.
The power control digital input wakes up the CM2115 when switched high to a
voltage of 3.9 V or greater, and turns the CM2115 off when switched low to a
voltage less than 1.4 V. The CM2115 also shuts off when an open circuit
condition occurs on the power control digital input.
5.3.2. Power Control Digital Input Installation Connections
You must be aware of the following when connecting power control inputs:
 The power control digital input is usually connected to the vehicle ignition,
but it can be connected to any power source in a system.
 When battery power (VBATT_LOGIC) is connected, and the power control
digital input is inactive, the CM2115 will go into sleep mode.
