Sequencer module for a pulse width modulation driver |
摘要 |
A driver for producing a desired pulse width modulated current through a load is provided with a sequencer for generating a plurality of wave forms phase-shifted so as to have non-overlapping duty cycles. A target generator supplies a target current value to a comparator, which compares the target current value to a signal representative of a sensed current flowing through the load. A driver control is responsive to a duty-cycle of only one of the plurality of wave forms to selectively generate trigger signals for switching current through the load in response to the result of the comparison.
