The VN330SP is a monolithic device made using STMicroelectronics VIPower technology, intended for driving four indipendent resistive or inductive loads with one side connected to ground. Active current limitation avoids dropping the system power supply in case of shorted load. Built-in thermal shut-down protects the chip from overtemperature and short circuit. The open drain diagnostic output indicates short circuit and overtemperature conditions.
The VN330SP is a monolithic quad high‑side smart power solid‑state relay designed to drive four independent resistive or inductive loads with one side connected to ground. It features active current limitation to protect the system power supply and built‑in thermal shut‑down for overload protection.
Key features include digital inputs clamped at 32 V minimum, shorted‑load and over‑temperature protections, an open‑drain diagnostic output, fast demagnetization of inductive loads, and a compact PowerSO‑10™ package with detailed mechanical dimensions.
