ZHCSO95B june 2022 – may 2023 TPS1641
PRODUCTION DATA
TPS1641x devices include power limiting or current limiting for a low power circuit (as per IEC60335 and UL60730 standards) in appliances, HVAC actuators, and medical equipment. TPS1641x devices also have IN to OUT short detection for internal FET for IN-OUT short testing during IEC60335 or UL60730 certifications. The TPS16410 and TPS16411 have an accurate power limiting feature while the TPS16412 and TPS16413 have an accurate current limiting feature. For transient current required for start-up of motors or actuators, TPS1641x devices have a configurable overcurrent protection threshold (IOCP) and configurable blanking time (IDLY/PDLY). For start-up with big capacitance (< 1 mF) on output, the TPS1641x include dVdT feature to control the output slew rate and limiting the inrush current during power up. The output current can be monitored from IOCP or IMON pin, by sensing the voltage on this pin.
