This application report describes the way to interface the TMS320C54x™ digital signal processor (DSP) with an I2C device. The setup uses the multichannel buffered serial port (McBSP) configured as general-purpose input/output port and is coupled with a timer interrupt to implement the I2C protocol. An attempt has been made to provide a glueless interface to the DSP. However due to the curr

The standard 12 V automotive battery rail can vary from 9 V-16 V during normal operation depending on load and charge. Under transients conditions battery voltages can range from 3 V to nearly 65 V. One of these extreme conditions is cold-crank. Cold-crank happens when the battery is trying to energize the starter of the engine and the battery voltage plummets to 3 V. Previousl

A limiter circuit consisting of an input buffer (A₁) an output-scaling amplifier (A₂) two zener diodes (Z₁ and Z₂) and several other components can supply sharp precise bipolar clamp levels with continuous variable control from 0 to ±11V. A feedback loop enclosing the amplifiers and zeners generates the high clamping accuracy.
