Texas Instruments TPS2640 42V 2A eFuses are compact, feature-rich, high voltage eFuses, with a full suite of protection features. The wide supply input range of 4.2V to 42V allows control of many popular DC bus voltages. The device can withstand and protect the loads from positive and negative supply voltages up to ±42V. Integrated back to back FETs provide a reverse current blocking feature making the device suitable for systems with output voltage holdup requirements during power fail and brownout conditions. Load, source, and device protection are provided with many adjustable features. These features include overcurrent, output slew rate, and overvoltage, undervoltage thresholds. The internal robust protection control blocks, along with the high voltage rating of the Texas Instruments TPS2640, helps simplify system designs for Surge protection.
A shutdown pin provides external control for enabling and disabling the internal FETs and places the device in a low current shutdown mode. For system status monitoring and downstream load control, the device provides fault and precise current monitor output. The MODE pin allows flexibility to configure the device between the three current-limiting fault responses (circuit breaker, latch off, and Auto-retry modes). The device is available in a 5mm × 4.4mm 16-pin HTSSOP package, as well as a 5mm x 4mm 24-pin VQFN package, and they are specified over a –40°C to +125°C temperature range.
