ZHCSNR7A March 2022 – August 2022 TPS55289
PRODUCTION DATA
The TPS55289 is protected by a thermal shutdown circuit that shuts down the device when the internal junction temperature exceeds 175°C (typical). The internal soft-start circuit is reset but all internal registers values remain unchanged when thermal shutdown is triggered. The converter automatically restarts when the junction temperature drops below the thermal shutdown hysteresis of 20°C below the thermal shutdown threshold.
