High-side switches can safely drive high currents into complex (resistive, inductive and capacitive) grounded loads in compliance with the harsh automotive environment. This requires both robust, low on-resistance power switch and accurate analog circuitry for diagnostic, protection and control functions.
ST’s high-side switches have 3 V and 5 V CMOS compatible inputs – for command – and outputs – for diagnostic and status – and are the perfect companions to a microcontroller.
Designed to work from -40 to +150°C, ST's high-side switches meet the stringent requirements set by international standards (such as AEC-Q100) and provide an extensive set of protection and diagnostic features such as:
ST's high-side switches portfolio includes single, dual and quad configurations and power switch on-resistance values starting from 4 mΩ with both digital and analog status diagnostic. They are available in multiple power-optimized packages to best cover body electronics applications such as junction box, interior lighting and motor control.
