The CAT4002BTD-GT3 is a power management integrated circuit (PMIC) in the form of an LED driver, a device that provides power to luminous elements such as LED light bulbs. LED drivers are used in a variety of applications, including automotive, indoor, and outdoor lighting. LED drivers are designed to accurately convert and regulate power to drive LED strings, providing protection against common risks such as overcurrent and overvoltage.

The CAT4002BTD-GT3 features an integrated FET switch, an operating frequency up to 1.2 MHz for improved compactness, and a wide input voltage range of 20V to 42V. It is an ideal solution for driving LEDs in automotive, truck, and off-road applications, including headlamps, brake lights, and signal lights. The CAT4002BTD-GT3 provides overcurrent protection, dip- and pulse-mode dimming, reverse-battery protection, and integrated thermalfoldback.

The CAT4002BTD-GT3 is a current-mode LED driver that operates with a fixed frequency of 1.2MHz. It provides a stable current source for controlling the current in an LED string. The device offers two dimming modes, dip-mode and pulse-mode dimming, both of which use external signal control circuitry to adjust the LED’s brightness. The device can be used in a variety of automotive, off-road, and warehouse applications.

The CAT4002BTD-GT3 can be used to drive up to four strings of LEDs in a variety of configurations. It is ideal for uses where the forward voltage and forward current of the LED string will remain relatively constant. The device’s maximum output current is limited to 1.25A and its maximum output voltage is limited to 42V.

In addition to its control features, the CAT4002BTD-GT3 provides several safety features, including reverse-battery protection, overcurrent protection, and an integrated thermalfoldback system that limits power consumption in the event of an overcurrent condition. The device also provides an open-drain Enable pin for disabling the LED string, as well as a Shutdown pin for controlling the LED string’s power state.

The CAT4002BTD-GT3 is a highly integrated device designed to meet the stringent requirements of automotive, off-road, and industrial applications. It is a reliable solution for providing power to LED-based lighting systems while offering protection against common risks and hazards. Its integrated features make it an ideal choice for designers looking to reduce their BOM count and save space in their PCB design while providing a safe and reliable power solution.
