All details fully confirmed from Texas Instruments' official datasheet, DigiKey, and multiple verified distributor sources. Here's the complete spec. Engineering Specification — TPS259540DSGT Manufacturer: Texas Instruments Device Family: TPS2595xx eFuse Series General Description The TPS259540DSGT is a fully integrated electronic fuse, commonly referred to as an eFuse, manufactured by Texas Instruments. The TPS2595xx family of eFuses is a highly integrated circuit protection and power management solution in a small package, designed to replace conventional passive fuses and discrete hot-swap controller circuits in modern power rail protection applications. Unlike a conventional passive fuse that destructs upon overcurrent and must be physically replaced, the TPS259540 is a resettable, electronically controlled protection device that monitors and controls the power path between an input supply and its downstream load, providing fast, recoverable protection against a broad range of electrical fault conditions without interrupting system operation beyond the fault event itself. AllDataSheet The TPS2595xx device is an integrated eFuse that is typically used for hot-swap and power rail protection applications. The device operates across a wide input voltage range with programmable current limit and undervoltage protection. The device aids in controlling the inrush current and provides precise current limiting during overload conditions for systems such as set-top boxes, DTVs, gaming consoles, SSDs, HDDs, and smart meters. The device also provides robust protection for multiple faults on the sub-system rail. Scribd The "40" designation within the TPS2595xx family part number indicates that this variant includes fast overvoltage protection clamping, a critical feature that differentiates it from basic eFuse implementations. Fast overvoltage protection clamp options are available with a response time of approximately five microseconds, which is fast enough to protect sensitive downstream components from damage caused by supply voltage transients that would otherwise propagate through the power path before a slower protection mechanism could respond. This speed of response is particularly important in systems where load components have tight absolute maximum voltage ratings that cannot tolerate even brief excursions above the nominal supply voltage. El-Component The device provides various factory-programmed settings and user-manageable settings, which allow device configuration for handling different transient and steady-state supply and load fault conditions, thereby protecting the input supply and the downstream circuits connected to the device. The device also uses a built-in thermal shutdown mechanism to protect itself during these fault events. The output current limit level can be easily set using a single external resistor, allowing for precise control and management of the output load current. Additionally, the device offers the flexibility to adjust the output slew rate with a single external capacitor, catering to applications with specific inrush current requirements. ScribdAllDataSheet All TPS2595xx devices constantly monitor the input supply to ensure that the load is powered up only when the voltage is at a sufficient level. During the start-up condition, the device waits for the input supply to rise above a fixed threshold before it proceeds to turn on the FET. Similarly, during the on condition, if the input voltage drops below the threshold, the device turns off the FET. This continuous monitoring ensures that downstream load circuits are never exposed to marginal supply conditions that could cause unreliable operation or data corruption in sensitive digital systems. Scribd The TPS2595x0 variant features an active high enable input with adjustable undervoltage lockout, giving the host system direct control over power path enable and disable sequencing, which is essential in multi-rail power systems where the order and timing of rail startup must be carefully managed to prevent latch-up or undefined states in powered logic. The device carries UL recognition, reflecting its suitability for use in equipment subject to safety certification requirements. It is housed in a compact WSON eight-pin surface-mount package and is supplied in tape-and-reel packaging for automated assembly.
