Suited for high-end industrial applications as well as outdoor equipment such as solar-power converters, electric vehicle charging stations, and industrial switched-mode power supplies, the STNRG ICs contain ST's State Machine Event Driven (SMED) high-resolution pulse-width modulation generator, in combination with an STM8-based supervisory core. These devices integrate a 32kbyte EEPROM, a 6kbyte RAM, an A/D converter, op amp, I2C port and GPIOs.
The STNRG family comprises: the STNRG288A, with four SMED-controlled outputs; the STNRG328A, with five SMEDs; and the STNRG388A, with six SMEDs. Designers have the option to connect two SMED cells together to generate dual gate drive signals with inserted dead time for half-bridge configurations.
