The POWR1220 -includes voltage monitoring for 14 inputs as well as trim settings -for output voltages and GPIOs. This driver implements the voltage -monitoring portion of the chip. - -Voltages are sampled by a 12-bit ADC with a step size of 2 mV. -An in-line attenuator allows measurements from 0 to 6 V. The -attenuator is enabled or disabled depending on the setting of the -input's max value. The driver will enable the attenuator for any -value over the low measurement range maximum of 2 V. - -The input naming convention is as follows: - -driver name pin name -in0 VMON1 -in1 VMON2 -in2 VMON3 -in2 VMON4 -in4 VMON5 -in5 VMON6 -in6 VMON7 -in7 VMON8 -in8 VMON9 -in9 VMON10 -in10 VMON11 -in11 VMON12 -in12 VCCA -in13 VCCINP - -The ADC readings are updated on request with a minimum period of 1s. |
