PRODUCTION DATA.
The TPS2660x is a family of high voltage industrial eFuses with integrated back-to-back MOSFETs and enhanced built-in protection circuitry. It provides robust protection for all systems and applications powered from 4.2 V to 60 V. The device can withstand ±60 V positive and negative supply voltages without damage. For hot-pluggable boards, the device provides hot-swap power management with in-rush current control and programmable output voltage slew rate features. Load, source and device protections are provided with many programmable features including overcurrent, overvoltage, undervoltage. The precision overcurrent limit (±5% at 1 A) helps to minimize over design of the input power supply, while the fast response short circuit protection 250 ns (typical) immediately isolates the faulty load from the input supply when a short circuit is detected.
The internal robust protection control blocks of the TPS2660x along with its ±60 V rating helps to simplify the system designs for the surge compliance ensuring complete protection of the load and the device.
The device provides precise monitoring of voltage bus for brown-out and overvoltage conditions and asserts fault signal for the downstream system. The TPS2660x monitor functions threshold accuracy of ±3% ensures tight supervision of the supply bus, eliminating the need for a separate supply voltage supervisor chip.
The device monitors V(IN) and V(OUT) to provide true reverse current blocking when a reverse condition or input power failure condition is detected. The TPS2660x is also designed to control redundant power supply systems. A pair of TPS2660x devices can be configured for Active ORing between the main power supply and the auxiliary power supply, (see the System Examples section).
Additional features of the TPS2660x include:
