A3942KLGTR-T Description

Short technical summary and product information.

The A3942KLGTR-T from Allegro Microsystems is a quad high-side gate driver IC engineered for demanding automotive environments. This device is capable of driving up to four N-channel MOSFETs in a high-side configuration, making it suitable for applications such as engine management, transmission systems, and body control actuators.

 

Key features include a wide input voltage range of 4.5V to 60V and an operating temperature range of -40°C to 125°C. The A3942KLGTR-T supports Serial Peripheral Interface (SPI) for control and fault diagnostics, alongside discrete inputs. It is available in a 38-lead thin TSSOP package (LG) with internally fused pins for enhanced thermal dissipation.

 

This IC is designed for driving inductive loads like glow plugs, valves, and solenoids. It incorporates several protection features, including short-to-ground detection, short-to-battery protection, open-load detection, VDD and VCP undervoltage lockout, and thermal monitoring. The device is lead (Pb) free with 100% matte tin leadframe plating.
