High-Side Switch

Southchip introduced the SC77450CQ, its second-generation automotive-grade High-Side Switch (HSD). This product marks a significant advancement, utilizing Southchip’s vertically integrated BCD process and a fully domestic supply chain. As the first high-side switch with complete domestic sourcing and integrated technology, the SC77450CQ challenges overseas dominance. Key features include: quad-channel configuration, low on-resistance (50mΩ), wide voltage range (4V-28V), high-precision current sensing (±4% at 2A), and comprehensive protection mechanisms suitable for automotive and industrial use.
