Performance Motor Integrated Circuits (PMICs) are key components in many applications, from low-end embedded systems to high-end industrial automation. Among them, motor drivers, controllers and regulators are especially important.SLA7050M is a member of such devices specifically designed for heavy duty motor control applications.

The SLA7050M is a pulse-width modulated (PWM) motor driver IC that offers both linear and non-linear control of high-power DC brush motors up to 200A peak (100A continuous). It is specially optimized for applications in ATVs, go-karts, boats and other types of manned or unmanned vehicles. This fully integrated driver offers a peak efficiency of up to 97%, and is suitable for motors ranging from 6V to 60V.

Impressively, the SLA7050M features both forward and reverse control, as well as braking action for up to 10A of current draw. It also supports two separate banks of setpoints for speed control, enabling designers to program two different speeds for a single motor controller. The device offers an adjustable switching frequency from 20 kHz to 140 kHz and an adjustable dead zone, allowing it to be tuned for any specific application. This also makes it one of the few solutions that offer ultra-low noise and low-harmonic distortion.

The SLA7050M is designed with a set of safety features. It snaps off or switches to a safety mode when it senses excessive motor current or low motor voltage. The three-channel over-current protective circuit (OCP) offers protection against over-current and over-voltage faults. The over-voltage protection can limit the voltage to a predetermined value larger or smaller than the main input voltage. It also shuts off or reduces the power dissipation when an over-temperature condition is detected.

In addition to its advanced safety features, the SLA7050M offers a unique “In this Mode” (ITM) feature that allows the user to program the minimum power consumption of their system. This feature reduces the power consumption of the system from its operating mode to its idle mode, depending on the configured parameters.

In terms of connectivity, the SLA7050M has integrated low voltage differential signaling (LVDS) communication interface. This provides designers with the flexibility to customize their driving profile for multiple load types and for specific applications.

The SLA7050M is built on a scalable architecture, allowing users to configure the number of channels to quickly scale up or down. It is available in an industry-standard 14-pin SOIC package, and with an operating temperature range of -40°C to 150°C.

Overall, the SLA7050M offers a comprehensive motor control solution for tasks ranging from low-power micro-stepping to full-control of large motors. It is equipped with programmable features and industry-standard safety features, and provides the user with maximum flexibility for each specific application. It is a great choice for designers looking for an efficient, robust and reliable solution for their motor control needs.
