Description

L4995AJTR is an STMicroelectronics motor-driver IC (part of the L4995A family). It is a compact dual full-bridge high-current driver designed for driving stepper motors or brushless DC (BLDC) motors in a single device.
Key points
- Integrates two high‑side/low‑side switches (power MOSFETs) and the required control logic for motor winding drive.
- Includes current regulation (via an external sense resistor), PWM current chopping, and options for microstepping control.
- Built-in protections: overcurrent, overtemperature, undervoltage, and fault/diagnostic outputs.
- Suitable for applications like printers, robotics, automation, CNCs, 3D printers, and automotive actuators.
- Packaging suffix AJTR indicates specific packaging/reeling (Tape & Reel) for automated assembly.
How to use (high level)
- Set the reference current with an external sense resistor.
- Drive the input pins with 3.3/5 V logic to control the two channels.
- Provide motor supply within the device’s recommended range and connect motor windings to the two channels.
- Refer to the L4995AJTR datasheet for exact pinout, electrical specs, and recommended application circuits.

Package

HTSSOP-28 package; TR indicates Tape & Reel packaging.

Pinout

Pin count: 16 pins (SO-16/TSSOP-16).
Function: STMicroelectronics L4995AJTR is a buck switching regulator controller intended for DC-DC conversion (automotive), typically used with an external power MOSFET. It provides PWM switching control, feedback, enable, current limit, and protection features.

Manufacturer

STMicroelectronics. It’s a multinational European semiconductor company that designs, develops, and manufactures integrated circuits and other electronic components for automotive, industrial, and consumer markets.

Application

Application areas of L4995AJTR:
- Automotive power management (12/24 V systems)
- Buck regulator for ECUs, infotainment, instrument clusters, and body electronics
- Industrial power supplies needing automotive-grade robustness and efficiency

Equivalent

L4995AJTR is STMicroelectronics’ primary-side regulation PWM controller for SMPS. There isn’t always a direct drop-in cross; functional equivalents (not guaranteed pin-compatible) include:
- TI UC3842/UC3843/UC3844
- ON Semiconductor NCP1200/NCP1250/NCP1251
- Richtek RT8250/RT8251 (primary-side controllers)
Always verify voltage, frequency, and pinout in datasheets; you may need redesign or an adapter. For exact cross references, check ST’s datasheet and distributor catalogs.
