Pulsed Command Interfaces and High Power Command (HPC) interface


 
Figure 4. HPC interface arrangement
 
Pulsed Command Interfaces are divided into:
  • High Power Command (HPC) interface
  • Low Power Command (LPC) interface
The high power pulse (HPC) command interfaces are intended for load driving interfaces and, for example, can be used to switch relays or similar loads. The high current capabilities of these interfaces lead to their protection against short circuiting and against failure in a high current mode. The high power pulse command consists of a single signal, HPC_OUT(H), generated by the core element. This is connected by a single ended circuit to the input at the peripheral element. The interface is entirely controlled from the core element. Three classes of HPC are defined here:
  • LV-HPC : low voltage HPC,
  • HV-HPC : high voltage HPC, and
  • HC-HPC : high current HPC

Figure 4 shows an electrical interface for HPC.
