External Temperature Sensing
As shown in Figure 2, the RT7204E provides the RT pin as a register-programmable current source to bias a
remote thermal sensor, such as a thermistor (NTC). If the RT voltage falls below the over-temperature protection
(OTP) threshold and the condition sustains for a programmed delay time, the OTP will be triggered.

Interface of D+ and D-
The D+ and D- pins are used for BC1.2 compliance or for communication with other proprietary protocols. The D+
and D- pins, connected to the MCU via an ADC, can be reprogrammed for other purposes, including acting as
analog or digital inputs or outputs, as shown in Figure 3.
