6.12.5 Comparator Subsystem (CMPSS)

The Comparator Subsystem (CMPSS) consists of analog comparators and supporting circuits that are useful for power applications such as peak current mode control, switched-mode power supply, power factor correction, voltage trip monitoring, and so forth.

This device contains two variants of the CMPSS module: CMPSS and CMPSS_LITE. These modules share a common architecture, but some features are supported only by the full CMPSS variant and not the CMPSS_LITE variant.

The comparator subsystem is built around a number of modules. Each subsystem contains two comparators, two reference 12-bit DACs (CMPSS_LITE instances are 9.5-bit effective reference DACs), and two digital filters. The subsystem also includes one ramp generator (full CMPSS modules only; not supported by CMPSS_LITE instances). Comparators are denoted "H" or "L" within each module where “H” and “L” represent high and low, respectively. Each comparator generates a digital output which indicates whether the voltage on the positive input is greater than the voltage on the negative input. The positive input of the comparator is driven from an external pin (see the Analog Subsystem chapter of the TMS320F280013x Real-Time Microcontrollers Technical Reference Manual for mux options available to the CMPSS). The negative input can be driven by an external pin or by the programmable reference 12-bit DAC. Each comparator output passes through a programmable digital filter that can remove spurious trip signals. An unfiltered output is also available if filtering is not required. A ramp generator circuit is optionally available to control the reference 12-bit DAC value for the high comparator in the subsystem (full CMPSS modules only; not supported by CMPSS_LITE instances).

Each CMPSS includes:

  • Two analog comparators
  • Two programmable reference 12-bit DACs (9.5-bit effective DACs on CMPSS_LITE instances)
  • One ramp generator (full CMPSS only; not available on CMPSS_LITE instances)
  • Two digital filters, 65536 max filter clock prescale
  • Ability to synchronize submodules with EPWMSYNCPER
  • Ability to extend clear signal with EPWMBLANK
  • Ability to synchronize output with SYSCLK
  • Ability to latch output
  • Ability to invert output
  • Option to use hysteresis on the input
  • Option for negative input of comparator to be driven by an external signal or by the reference DAC
  • Option to use the low comparator DAC output, CMPx_DACL, on an external pin (select instances only, mutually exclusive with use of compare functionality)
