Configurable high-side/low-side drivers

8 July 2009 Power Electronics / Power Management

The new Spider configurable high-side/low-side modular family from Infineon comes with a standard 8-channel output incorporating two low-side drivers, four high-side drivers and two auto-configuring drivers. These can be used in high-side or low-side configurations just by connecting the load accordingly. Protective and diagnostic functions adjust automatically to the chosen configuration. The serial peripheral interface is utilised for control and diagnosis of the device and the loads. It provides daisy-chain capability in order to assemble multiple devices in one SPI chain while using the same number of microcontroller pins. The devices are equipped with up to three input pins that can be individually routed to the output control of some channels, thus offering flexibility in design and PCB layout.
