ST’s intelligent high-side switches provide one or more channel bipolar/MOSFET output switches to drive inductive, capacitive or resistive loads. Diagnostics for CPU feedback and extensive use of electrical protection features make these devices inherently indestructible and suitable for industrial applications. These devices operate over a wide range of voltages: from +5.5 up to +50 V.

Galvanic isolated 8-channel high-side switch in compact QFN package

Smaller, more robust and energy-efficient controllers are the current trend for innovative industrial automation equipment. An octal integrated galvanic isolated switch, ST’s ISO8200BQ housed in a compact QFN package fulfills the safety requirements and saves the PC-board space occupied by conventional opto-electronic isolation circuitry. With very low levels of quiescent current, together with on-chip RF communication through the isolation layer, it ensures excellent levels of efficiency and immunity to electromagnetic noise and ESD in compliance with international standards.
