3.6 Power & Voltage Monitoring
3.6.1 Power Monitor
Pow er monitors are provided on the module. These monitor the main DC, CPU, GPU/SRAM, SOC (CORE) & DDR Supplies.
The monitors w ill toggle a WARN (w arning) output, or a CRIT (critical) output, depending on the pow er “seen” at the sense
resistors and the thresholds set for each supply.

3.6.2 Voltage Monitor
Jetson TX2i
A voltage monitor circuit is implemented on Jetson TX2i to indicate if the main DC input rail, VDD_IN, “droops” below an
acceptable level. The device used w ill react quickly and drive VIN_PWR_BAD# active (low ) w hich w ill force the pow er off. The
voltage monitor circuit is implemented w ith a fast voltage comparator supplied by VDD_IN w ith a 5V reference. This device has
an open drain active low output w hich is pulled low w hen the VDD_IN voltage drops below the selected threshold (8.04V).
