The Infineon Technologies IR21592STR is a versatile Ballast Controller IC that integrates ballast control and half-bridge driver functionalities into a single package. It is designed for dimmable ballast applications, offering features such as transformer-less lamp power sensing and closed-loop control for both lamp power and preheat current.
Key electrical specifications include an operating voltage range of 12V to 16.5V and a supply current of 10 mA. The operating frequency can be adjusted between 18kHz and 95kHz, with programmable minimum frequency settings. The device supports dimming control via a 0.5 to 5VDC input and includes adjustments for minimum and maximum lamp power.
Designed for robust operation, the IR21592STR incorporates features like lamp ignition detection, programmable preheat and ignition-to-dim times, and full lamp fault protection. It also includes brown-out protection, automatic restart, micro-power startup, and over-temperature protection. The operating temperature range is -40°C to 125°C.
This IC is housed in a 16-SOIC surface mount package, with a supplier device package also specified as 16-SOIC. The standard package quantity is 2500 units on tape and reel.
