STA515W is a monolithic quad half-bridge stage in Multipower BCD Technology. Its main features include: Multipower BCD technology, low input/output pulse width distortion, 200 mΩ RdsON complementary DMOS output stage, CMOS-compatible logic inputs, thermal protection, thermal warning output, undervoltage protection and short-circuit protection
The STA515W is a monolithic quad half-bridge stage designed in Multipower BCD Technology. It serves as an output stage for stereo all-digital high-efficiency amplifiers, capable of delivering up to 40 W into an 8-Ω load with 10% THD at Voc = 26 V in single parallel BTL configuration.
The device includes integrated bridge drivers, high-efficiency MOSFET outputs, and comprehensive protection circuitry for thermal shutdown, short-circuit conditions, and undervoltage lockout. It features CMOS-compatible logic inputs and is available in a 36-pin PowerSSO package with an exposed pad.
