Overview
The A2550KLPTR-T is a buffer or inverter-based peripheral driver manufactured by Allegro Microsystems. It features a 16-pin TSSOP package and operates within a temperature range of -40 °C to 125 °C. The device provides an output current capability of 0.25 A with source output current flow. It includes built-in protections for transient, over-current, over-voltage, thermal, and under-voltage conditions.
Feature Summary
- Integrated protection mechanisms including over-current, over-voltage, thermal, and under-voltage safeguards
- Designed as a buffer or inverter based peripheral driver interface circuit
- Capable of sourcing up to 0.25 A output current
Applications
- Peripheral driver interface circuits
- Buffer or inverter applications requiring integrated protection
Procurement Notes
Verify the specific package variant, as datasheets may list both HTSSOP and TSSOP designations for this part number. Confirm that the 0.25 A output current rating aligns with your load requirements. Ensure the operating temperature range of -40 °C to 125 °C meets your environmental specifications before finalizing procurement.
Selection Notes
Select this component when a single-channel driver with integrated fault protection is required. The 0.25 A source current limit defines its suitability for low-to-medium power peripheral loads. Consider the 16-pin form factor for board space constraints. Verify compatibility with the intended logic levels and voltage domains for the peripheral being driven.
Part Context
This component belongs to the Allegro MicroSystems lineup of analog mixed-signal ICs. It functions specifically within the drivers and interfaces category. The device is designed for robust operation in automotive or industrial environments given its extended temperature range and comprehensive protection suite.
Replacement Considerations
No direct public substitute part numbers are identified in the provided documentation. Evaluate other Allegro buffer drivers or generic equivalents only if they match the 16-pin TSSOP/HTSSOP footprint, 0.25 A current capacity, and protection features.
