Application Notes
- A Power-Distribution Switch With Latched Over-Current Protection (Rev. A)PDF, 99 Kb, Revision: A, File published: Jul 3, 2007
Power-distribution switches, like the TPS203x, operate in retry mode in an overload, but some applications require the switch to latch off. The latch-off function can be implemented using the simple circuit described in this application report.
