The E-L9935 is an integrated half-bridge motor driver and controller, designed to provide a dedicated solution for brush and brushless motors that require high efficiency and performance. With a wide input voltage range of 5.5–46V, the E-L9935 operates over a wide temperature range of -40°C to +150°C, and its advanced motor control, diagnostic and protection functions enable better system reliability and compatibility.

At the heart of the E-L9935 lies a two-phase motor-driver with fast on-off and variable PWM speed control. This two-phase motor driver is capable of providing a peak current of 12A and a continuous current of 6A. This high current capacity enables the E-L9935 to power and drive large motors, providing high efficiency across the whole speed range and providing the system with higher power and torque levels.

In addition to the motor-driver, the E-L9935 also includes many other features that make it well-suited for use in a wide range of applications. These features include a built-in high-resolution 16-bit ADC, enabling precise motor speed control, a serial-interfacable RPM counter for feedback speed control, pulse-width modulation (PWM) and bridge short-circuit protection for short-circuit protection, and a non-volatile memory for storing user settings.

The E-L9935 also features a sophisticated thermal protection system with multiple temperature-sensing settings, which can be used to protect the device against excessive temperatures. This system can be configured via software and is used to ensure steady and efficient operation within the laid-out temperature limits.

In addition, the E-L9935 has onboard power sequencing capabilities which ensure that there is no voltage drop due to sudden connection. This feature can be used to avoid system-failure due to the inappropriate power-ups, and the E-L9935 can also be used in applications that require pre-charging of capacitors before the motor is connected.

Overall, the E-L9935 is an ideal choice for motor control and power supply applications, such as in agricultural machinery, robotics, medical equipment, HVAC systems and consumer appliances, as it offers high efficiency, robust protection functions and operational flexibility.
