The A3941KLPTR-T from Allegro Microsystems is a full-bridge controller specifically engineered for automotive applications utilizing external N-channel power MOSFETs to drive high-power inductive loads, such as brush DC motors.
This driver features a wide supply voltage range of 5.5V to 50V, supported by a unique charge pump regulator that provides full gate drive even at battery voltages as low as 7V. It allows for DC (100% duty cycle) operation through an internal charge pump for the high-side drive. The device supports fast or slow decay modes with diode or synchronous rectification, and includes resistor-adjustable dead time for shoot-through protection.
Integrated diagnostics offer indications for undervoltage, overtemperature, and power bridge faults, enhancing protection capabilities. The A3941KLPTR-T is supplied in a 28-pin TSSOP power package with an exposed thermal pad, suitable for surface mounting. The package is lead-free with 100% matte-tin leadframe plating.
