TPS25940-Q1 SLVSDJ0C – MAY 2016 – REVISED JULY 2018 TPS25940x-Q1 2.7-V to 18-V eFuse with Integrated Short-to-Battery Protection 1 1 Features 1 • Qualified for Automotive Applications • AEC-Q100 Qualified With the Following Results: – Device Temperature Grade 1: –40°C to +125°C Ambient Operating Temperature Range – Device HBM ESD Classification Level 2 – Device CDM ESD Classification Level C5 • 2.7-V to 18-V Operating Voltage, 20 V (Maximum) • Total RON: 42 mΩ (Typical) • 0.6-A to 5.3-A Adjustable Current Limit (±8%) • IMON Current Indicator Output (±8%) • Adjustable Under-, Overvoltage Threshold (±2%) • Reverse Current Blocking • 1-μs Reverse Voltage Shutoff • Programmable dVo/dt Control • Power Good and Fault Outputs • Short-to-Battery Protection • Short-to-Ground Protection • TPS25940-Q1: Auto-Retry • TPS25940L-Q1: Latch-Off 2 Applications • Automotive Infotainment • ADAS Cameras and Radar Sensors • USB Hubs • Power MUXing • Holdup Power Management 3 Description The TPS25940x-Q1 eFuse Power Switches are compact, feature rich power management devices with a full suite of protection functions. The wide operating range allows control of many popular DC bus voltages. Integrated back-to-back FETs provide bidirectional current control making the device well suited for systems with load side holdup energy that must not drain back to a failed supply bus. Load, source and device protection are provided with many programmable features including overcurrent, dVo/dt ramp and overvoltage, undervoltage thresholds. For system status monitoring and downstream load control, the device provides PGOOD, FLT and precise current monitor output. Precise programmable undervoltage, overvoltage thresholds and mode simplify power management design. The TPS25940x-Q1 monitor V(IN) and V(OUT) to provide true reverse current blocking when V(IN) < (V(OUT) – 66 mV). This function supports supply bus protection from over-voltages during output short to battery faults.
