8.3.5.2 Overtemperature Protection

The TMAG5115 features overtemperature protection to prevent damage to the device and system in the case of runaway thermal heating. If the output is short-circuited, there will be greater power dissipation through the device causing the junction temperature to rise. If the temperature rises to above the limits specified in the Electrical Characteristics table, the device will enter a thermal shutdown and the OUT pin will turn to High-Z regardless of the current magnetic field detected.

The TMAG5115 thermal shutdown can be differentiated from normal operation by viewing the supply current into the device. While in thermal shutdown, the supply current is lower than normal operation.

The TMAG5115 can support a supply voltage of 2.5 V to 26 V. Higher temperature and supply conditions can increase the junction temperature of the device, however, which could exceed the thermal shutdown limit. This can cause a device shutdown. TI recommends to not exceed a temperature and supply combination shown in Figure 8-9.
