ZHCSNW8A October 2022 – December 2022 LMG2610
PRODUCTION DATA
The over-temperature protection holds off both the low-side and high-side GaN power FETs if the LMG2610 temperature is above the over-temperature shut-down temperature. The over-temperature shut-down hysteresis avoids erratic thermal cycling. An over-temperature fault is reported on the FLT pin when the over-temperature protection is asserted. This is the only fault event reported on the FLT pin. The over-temperature protection is enabled when the AUX voltage is above the AUX Power-On Reset voltage. The low AUX Power-On Reset voltage helps the over-temperature protection remain operational when the AUX rail droops during the cool-down phase.
