The MIC4834YMM-TR is a LED ballast controller that offers protected PWM control of LED ballast stages and offers improved performance and better energy efficiency. The product works with multiple LED stages, each stage running up to 20 A with 200 ns control loop response time and advanced diagnostics. The device has integrated, high-voltage drive FETs that allow operation with 12 to 24 V input voltages, making it ideally suited for applications requiring reliable performance and high efficiency.

The MIC4834YMM-TR\'s feature set can be divided into three functions: current sensing, timing control and monitoring. Current sensing is achieved through integrated analog current-sense amplifiers, which can be adjusted for optimal current sensing range. Timing control is delivered through integrated high-voltage drive FETs, allowing for configurable on/off times without external components. The integrated monitor circuit continuously monitors the current and allows for remote monitoring of the LED stages status.

The MIC4834YMM-TR allows for complex lighting solutions qualified for a variety of commercial and industrial applications. With its integrated 4-channel PWM dimming support and advanced diagnostic features, it can help reduce energy usage while providing reliable performance. And by eliminating the need for external components, its lower bill-of-materials (BOM) cost contributes to improved performance, higher efficiency and cost savings.

The MIC4834YMM-TR can also be used to deliver constant illumination in multiple environments. The device\'s internal protection circuitry helps protect against voltage overshoots and under-voltage conditions, making it ideal for emergency lighting applications. With it, users can programmatically limit current ramp-up time and prevent current shoot-through overshoot. The product also supports multiple frequency setting options, allowing for multiple illumination levels. So regardless of the environment, users can control the LED stages brightness as needed.

In addition, the MIC4834YMM-TR provides a range of added features such as temperature monitoring, integrated open-drain output for load shutdown, input over-voltage protection and EMI suppression. These features help ensure reliable performance and secure protection for connected lighting systems.

Finally, the MIC4834YMM-TR exceeds the most stringent requirements for automotive, IEC and mobile device Lighting applications. It is available in a 16-pin TSSOP package, is AEC-Q100 Grade 3 qualified, and is RoHS compliant.

All in all, the MIC4834YMM-TR is an advanced LED ballast controller designed to offer high performance and energy-efficient lighting solutions for various commercial and industrial applications. It provides integrated current sensing, timing control and monitoring functions, eliminating the need for external components and cutting down on BOM costs. It also offers multiple protections to help ensure reliable performance and secure protection for connected lighting systems. Thanks to its added features, the MIC4834YMM-TR delivers a great combination of reliable performance, higher efficiency and cost savings.
