Abstract
A multi-channel remote diode temperature sensor includes a variable current supply configured to provide a base or an elevated current, a bias circuit, an analog-to-digital converter having a first and second input terminals, a logic block and a switch arrangement. The switch arrangement cooperates with the logic block to electrically connect the current supply, bias circuit and analog-to-digital input terminals to first and second data pins. Pairs of anode-to-cathode connected remote diodes in electrical communication with the data pins are monitored by measuring the difference in forward voltages at the two currents. Reversal of the configuration of the switch arrangement paths permits monitoring of the other member of the anode-to-cathode remote diode.
