Abstract
Circuits and apparatus for delivering a constant-current pulse with stability compensation into low impedance pyrotechnic loads are disclosed. One apparatus includes a power switch circuit including a high side connectable to an external device and for outputting current to the external device, a current sense circuit connected to the power switch circuit and for monitoring and limiting an amount of the current being output by the power switch circuit, a compensation circuit connected between the current sense circuit and the high side of the power switch circuit. The compensation circuit includes circuitry to provide gain and phase margin over a frequency range that provides stability in the current being output by the power switch circuit over a range of temperatures, input voltages, load impedances, and harness lengths. Systems that include the apparatus and/or perform the operations of the apparatus are also disclosed.
