PM8804TR Image

The PM8804TR from STMicroelectronics is a Peak Current Mode Controller IC that is ideal for power-over-ethernet (PoE)-enabled devices such as IP phones, WLAN access points, network cameras, and telecom power supply applications. It requires an input voltage of up to 75 V. This IC has been designed for high efficiency and supports various topologies such as flyback, forward, and flyback with synchronous rectification. It features a programmable oscillator for adjusting the frequency and slope compensation along with dual complementary low-side drivers with customizable dead time. This PoE IC offers a range of programmable functionalities, including soft-start, soft-turn-off, and current sense blanking time to ensure protection of load circuits and components. It is also equipped with embedded protections, including severe over-current protection with latch, delayed over-load protection with automatic restart, and feedback disconnection protection (over-voltage) to prevent short-circuit-related damages. This IC is available in a surface-mount package that measures 3.0 x 3.0 mm.
