ZHCSQ35 November 2022 TPA3223
PRODUCTION DATA
TPA3223 has a two-level temperature-protection system that asserts an active-low warning signal ( OTW_CLIP) when the device junction temperature exceeds 125°C (typical). If the device junction temperature exceeds 155°C (typical), then the device is put into thermal shutdown, resulting in all half-bridge outputs being set in the high-impedance (Hi-Z) state and FAULT being asserted low. OTE is latched in this case. To clear the OTE latch, RESET must be asserted. Thereafter, the device resumes normal operation.
