LTC1157CS8#TRPBF

Overview

The LTC1157CS8#TRPBF is a dual MOSFET gate driver manufactured by Analog Devices Inc., housed in an SOIC-8 surface-mount package. It integrates high-side and low-side drivers for microprocessor-controlled applications, operating on a supply voltage range of 2.7 V to 5.5 V with a maximum input voltage of 7 V. The device features a quiescent current of 180 uA and delivers an output voltage of 8.8 V. It supports a maximum dead time of 60 us and functions within a temperature range of 0 C to +70 C.

Feature Summary

• Integrates both high-side and low-side drivers for complete half-bridge control
• Optimized for direct interface with standard microprocessors
• Provides independent control inputs for precise switching timing

Applications

• Microprocessor-controlled power supplies
• DC-to-DC converter circuits
• Motor drive systems

Procurement Notes

Verify the specific suffix against official documentation to confirm tape-and-reel packaging versus tube variants. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Ensure component authenticity via authorized distribution channels to mitigate counterfeit risks.

Selection Notes

Select this component when a compact dual-driver solution is required for low-voltage logic interfaces. Evaluate the 2.7 V minimum supply requirement against system rails. Consider the SOIC-8 footprint constraints and thermal dissipation capabilities relative to the expected load current demands.

Part Context

This part belongs to the LTC1157 series of specialized gate drivers designed for efficiency in embedded power management. It complements other Analog Devices PMICs by providing robust switching control for external MOSFETs in space-constrained designs.

Replacement Considerations

Consult official substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully before implementation.
