The internal temperature sensor is disabled as default. Figure 7-15. Internal Temp Sensor Temperature sensor is calibrated at room temperature (25°C) via a calibration register value. The temperature sensor is measured using ADC12 (via Ch14). The temperature is then calculated using a mathematical formula involving the calibration register (this effectively adds a delta to the ADC measurement). The temperature sensor can be enabled or disabled. 7.5.11 I/O Mux Control In different packages of UCD3138A several I/O functions are multiplexed and routed toward a single physical pin. I/O Mux Control register may be used in order to choose a single specific functionality that is desired to be assigned to a physical device pin for your application. 7.5.12 Current Sharing Control UCD3138A provides three separate modes of current sharing operation. • Analog bus current sharing • PWM bus current sharing • Master/Slave current sharing • AD02 has a special ESD protection mechanism that prevents the pin from pulling down the current- share bus if power is missing from the UCD3138A |
