Bus-Connected Point-Of-Load Output Driver - Single Output

Synopsis

Single, point-of-use, high-current-capacity output driver that can receive control codes via CAN from a bus-connected input processor or other device

 

Full Description

The Bus-Connected Point-Of-Load Output Driver is a universal device intended to work in concert with an Input Processor, with driver receiving and acting on commands sent from the Input Processor in response to activities on its input ports. By utilizing a data bus for commands, small-signal inputs with low current can effectively remotely control larger currents elsewhere in the vehicle.

This project entails the construction of a device with a single high-current switch (specifically, a solid-state relay) that can be used to control the current flow to one item or circuit. By utilizing a switch design instead of merely sourcing or sinking current, the device can drive a load via high or low side. Please note that another version of this project exists that is intended for use as a motor controller - it provides polarity-reversible motor control via high-current "H" bridge.

The programmable nature of the input controller, coupled with the application versatility of this driver, makes it possible to easily use it to perform complex actions such as operating all of the power windows and door locks in a vehicle.

Design Goals

This project includes the following design goals in addition to, or in substitution of, the standard project design rules for Initiative projects:

• N.O. contacts must not be polarity-specific. Bidirectional switching is required.
• Control circuitry and output driver must be isolated.
• Current safety margin must exceed 2:1 (60A minimum).
• In addition to surviving load dumps, switched side must survive significant back-EM spikes from breaking current flow through inductive loads.
