PMIC - Motor Drivers, Controllers are kinds of integrated circuits (ICs) which are used to interface motors with other system components. A3922KLPTR-T is one such motor driver controller IC which offers complete motor control solutions for applications such as brushed DC motors and other brushed motors with two windings

The A3922KLPTR-T is development based on a low voltage drop, high efficiency power MOSFET driver IC and a microcontroller (MCU). It combines together the operation of an integrated driver and the high performance of a digital circuit. This IC supports various convenient operation modes, including motion control, speed regulation and pulse width modulation.

Applications of the A3922KLPTR-T include robot arms, smart phones, printers, home appliances and other automation systems. This IC requires an operating voltage of 1.8V to 5.5V and any voltage within this range can be selected. It also has on-chip ESD protection and protections against over-voltage, over-current and under-voltage.

A3922KLPTR-T integrates 4 half-bridge drivers, two low-side current sense resistors in and two PWM gates , each of which can be individually enabled. It features dynamic Sleep/Active control, integrated dynamic brake control and provides the CPU with FET shut-down, open-phase, over-current and short-circuit fault information . In addition, the stroke count and detected external speed are provided with secure storage via an on-chip register.

The A3922KLPTR-T also integrates two configurable PWMs for 5-bit speed control and 16-bit pulse width control. This PWM can be used to modulate speed, acceleration and deceleration. The digital loop control function provides the current sensing loop and the voltage loop, thereby simplifying system layout. It also supports the non-directional motion control, rotational motion control and interlocked turning direction control.

The A3922KLPTR-T is a highly sophisticated motor driver controller IC with low power consumption and superior accuracy. It can be used in a wide range of applications and its features provide a great amount of flexibility and efficiency in the operation of such applications. The device is also protected by a number of fail-safes which allows it to be used with confidence even in the harsher of environments. As such, the A3922KLPTR-T is a good choice for applications requiring reliable and efficient motor control.
