LTC1623CS8#PBF

Overview

The LTC1623CS8#PBF is a dual high-side switch controller manufactured by Analog Devices Inc., housed in an 8-lead SOIC package. It operates on a supply voltage range of 2.7 V to 5.5 V and supports two independent drivers with corresponding outputs. The device features a rise time of 1 µs and a fall time of 300 ns, functioning within a temperature range of 0°C to +70°C.

Feature Summary

• Integrates two high-side gate drivers for independent control
• Supports SMBus interface communication
• Provides bidirectional buffering between bus lines

Applications

• SMBus controlled power distribution systems
• Hot-swap controller applications
• Multi-voltage level translation interfaces

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the SOIC-8 package dimensions match the target PCB footprint. Ensure the operating environment remains within the specified 0°C to +70°C commercial temperature range to maintain performance specifications.

Selection Notes

Select this component when dual high-side switching with SMBus control is required. Verify that the input logic levels are compatible with the system's microcontroller or host processor. Consider the thermal dissipation capabilities of the SOIC-8 package relative to the expected load current and ambient conditions during continuous operation.

Part Context

This part belongs to the LTC1623 series of hot-swappable bus buffers and controllers. It is designed for applications requiring safe insertion and removal of cards into live backplanes while maintaining data integrity on the I/O bus. The device isolates card capacitance from the backplane until connection is established.

Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pinout configuration and electrical characteristics for direct replacement.
