The LTC4243 contains four switches, each with an independent circuit breaker function and a synchronized sense switch. Each switch can operate completely autonomously or be arbitrarily grouped with other switches that respond together to the fault of any device within its group. Optionally, channel grouping can be extended to multiple LTC4243 devices by selecting the FIN# (fault input) pin as part of a channel group. A required bias supply between 2.6 V to 5 V allows the switches to independently operate from 20 V down to 0 V. The LTC4243 provides an SPI to enable, disable, and configure the timing and current thresholds of each channel as well as provide status to each channel’s fault state.A common open-drain FAULT status output indicates if any switch has opened due to a circuit breaker event.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
LTC4243 is an authentic electronic component manufactured by Analog Devices, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official LTC4243 datasheet above.
Electronic component spot-market pricing for LTC4243 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for LTC4243 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
