PSoC 4 Power Monitor

2020 年 6 月 11 日

  • Interfaces to up to 8 DC-DC power converters
  • Measures power converter output voltages using a SAR ADC
  • Monitors the health of the power converters generating warnings and faults based on user-defined thresholds


Power Converter Voltage Measurements:

For power converter voltage measurements, the ADC shall be configured into single-ended mode. The ADC can also be configured to use bypass capacitor or not. In cases where the analog voltage to be monitored equals or exceeds Vdda or the ADC range, external resistor dividers are recommended to scale the monitored voltages down to an appropriate range.

ADC Sequential Scanning:

The ADC sequences through all power converters, if enabled, in a round-robin fashion, taking voltage measurements. This Component measures the voltages of all the power converters in the system.

This Component needs some knowledge of Components external to the PSoC device, because scaling factors for input voltages that have been attenuated to meet IO input range limits or ADC dynamic range limits where applicable.
