L4995AJTR

Introduction to L4995AJTR
- What it is: STMicroelectronics’ L4995AJTR is a motor-driver IC (L4995A family), delivered in a tape-and-reel (TR) package.
- Purpose: Designed to drive brushless DC (BLDC) and/or stepper motors in automotive and industrial applications.
- Key features (typical): motor-control circuitry with current regulation, supports PWM/analog control, and includes protections such as overcurrent, undervoltage, and thermal shutdown with fault reporting.
- How it’s used: external current-sense resistor sets motor current; control signals from a microcontroller regulate motor operation.
- Packaging: AJTR indicates the specific package and reel packaging.
- For exact specs: refer to the official datasheet and product page for pinout, voltage/current limits, timing, and environmental ratings.

- Pin count: 16 pins (SO-16 package)
- Function: PWM controller IC for a DC-DC switching regulator (buck converter), typically used with external MOSFETs; automotive-grade.

- Manufacturer: STMicroelectronics.
- What kind of company: A multinational semiconductor and electronics company that designs and manufactures integrated circuits and discrete components for automotive, industrial, and consumer applications.

L4995AJTR is a high‑efficiency, high‑current step‑down controller for automotive and industrial SMPS. Typical applications include:
- Automotive DC‑DC regulators (24V networks, ECUs, infotainment)
- Industrial/consumer switch‑mode power supplies (buck regulators, point‑of‑load rails)
- Battery‑powered equipment and portable devices
- LED drivers and lighting power supplies
- Motor control and power electronics for small to mid‑size drives
