Overview
The A5929KLPTR-T is a full-bridge MOSFET gate driver designed for Brushless DC (BLDC) motor applications, featuring integrated current sense amplifier (CSA) avoidance. Manufactured by Allegro MicroSystems, it operates within a supply voltage range of 5.5 V to 50 V and supports junction temperatures from -40 °C to +150 °C. The device utilizes a TSSOP-24 surface-mount package and delivers a 13 V output drive voltage. Key electrical specifications include a maximum propagation delay of 180 ns, a minimum dead time of 20 ns, and an operating supply current of 6 mA.
Feature Summary
- Integrated BLDC gate driver architecture optimized for brushless motor control
- Full-bridge configuration supporting high-side and low-side MOSFET driving
- Automotive-grade thermal performance with extended temperature operation up to 150 °C
Applications
- Brushless DC (BLDC) motor gate driving in automotive systems
- Industrial motor control applications requiring robust bridge drivers
- General-purpose power management IC integration for motor drives
Procurement Notes
Verify the specific ordering suffix and package variant against the manufacturer's official datasheet before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the component matches the exact part number A5929KLPTR-T to guarantee compatibility with intended BLDC gate driver designs.
Selection Notes
Select this component when designing BLDC motor interfaces that require a dedicated full-bridge gate driver with integrated protection features. It is suitable for applications demanding wide input voltage ranges and high thermal stability. Consider the TSSOP-24 footprint and 180 ns propagation delay characteristics during PCB layout and timing analysis.
Part Context
This component belongs to the A5925 series family from Allegro MicroSystems. It is categorized under PMIC - Power Management ICs and specifically falls within the MOSFET Gate Drivers subcategory. The device is distinct from brushed DC motor drivers or LED lighting drivers found in other product lines.
Replacement Considerations
Consult official Allegro MicroSystems documentation for verified cross-reference part numbers. Do not assume functional equivalence with other bridge drivers without verifying pinout, voltage ratings, and interface specifications.
