Frequently Asked Questions
Up to what supply voltage can the LTC4357CMS8#TRPBF control an N-channel hot-swap MOSFET?
The LTC4357CMS8#TRPBF supports positive-rail hot-swap control up to 80 V, making it compatible with 12 V automotive, 24 V industrial, and 48 V telecom bus architectures. Its wide input voltage range eliminates the need for separate controllers in multi-rail systems where bus voltages vary significantly.
How does the LTC4357CMS8#TRPBF limit inrush current when a board is hot-inserted?
The LTC4357CMS8#TRPBF controls the gate rise time of an external N-channel MOSFET, slowing the power-up ramp to limit inrush current. The inrush rate is set by an external sense resistor and gate capacitance, allowing designers to achieve inrush currents below 1 A even when charging large bulk capacitors of 100 µF or more.
For an 8-pin MSOP footprint constraint, how does the LTC4357CMS8#TRPBF compare to competing hot-swap controllers in board area?
The 8-pin MSOP package of the LTC4357CMS8#TRPBF occupies approximately 15 mm² of board area, which is significantly smaller than DIP-8 alternatives consuming over 60 mm². This compact footprint, combined with 80 V capability, makes it favorable for space-constrained automotive modules where high-voltage protection and size are both critical design constraints.
