SPARK MAX Specifications

We're Updating our Documentation! For the most up-to-date information about the SPARK MAX and other ION Motor Controllers please check out the following new documentation pages:

• REV ION Brushless

  • SPARK MAX Resources

  • REVLib for SPARK MAX

• REV Hardware Client Documentation

The following tables provide the operating and mechanical specifications for the SPARK MAX motor controller.

DO NOT exceed the maximum electrical specifications. Doing so will cause permanent damage to the SPARK MAX and will void the warranty.

Main Electrical Specifications

Parameter	Min	Typ	Max	Units
Operating Voltage Range	5.5	12	24	V
Absolute Maximum Supply Voltage	-	-	30	V
Continuous Output Current	-	-	60*	A
Maximum Output Current (2 second surge)	-	-	100	A
Output Frequency	-	20	-	kHz

*Continuous operation at 60A may produce high temperatures on the heat sink. Caution should be taken when handling the SPARK MAX if it has been running at higher current level for an extended period of time.

If using a battery to power SPARK MAX, make sure the fully charged voltage is below 24V allowing for sustained operation. Some battery chemistries and configurations, including 6S LiPo packs, have a charge voltage above the maximum operating voltage for SPARK MAX.

PWM Input Specifications

Parameter	Min	Typ	Max	Units
Full-reverse Input Pulse †	-	1000	-	μs
Neutral Input Pulse ††	-	1500	-	μs
Full-forward Input Pulse †††	-	2000	-	μs
Valid Input Pulse Range	500	-	2500	μs
Input Frequency	50	-	200	Hz
Input Timeout ‡	-	50	-	ms
Default Input Deadband ‡‡	-	5	-	%
Input High Level	0.5	0.7	0.9	V
Input Voltage Max	12	-	-	V

†	Brushed: between A and B outputs at 100% duty. Brushless: A->B->C direction at 100% duty.
††	Neutral corresponds to zero output voltage (0 V) and is either braking or coasting depending on the current idle behavior mode.
†††	Brushed: between A and B outputs at 100% duty. Brushless: C->B->A direction at 100% duty.
‡	If a valid pulse isn't received within the timeout period, the SPARK MAX will disable its output.
‡‡	Input deadband is added to each side of the neutral pulse width. Within the deadband, output state is neutral. The deadband value is configurable using the REV Hardware Client or through the CAN interface.
