LTC1255CN8#PBF

Overview

The LTC1255CN8#PBF is a dual high-side MOSFET gate driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 9 V to 24 V and supports input voltages up to 30 V. The device features two independent drivers with a maximum quiescent current of 600 uA and an output drive capability of 23 uA. It provides a maximum dead time of 60 us and delivers an output voltage of 10.5 V. Designed for through-hole mounting, it is housed in an 8-pin PDIP package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-channel architecture providing independent control for high-side MOSFET applications
• Integrated dead-time generation mechanism to prevent shoot-through conditions
• Robust input tolerance supporting signal levels up to 30 V

Applications

• High-side switching in power management circuits
• MOSFET gate driving in industrial motor control systems
• Power conversion topologies requiring isolated or floating high-side drive

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the PDIP-8 package type matches your PCB footprint requirements. Ensure the 9 V minimum supply voltage aligns with your system's available rail. Check that the 0°C to +70°C commercial temperature range meets your environmental specifications before finalizing procurement.

Selection Notes

Select this component when a dual high-side driver is required for synchronous rectification or half-bridge configurations. The 24 V maximum supply limit defines its suitability for lower voltage power stages. Consider the 600 uA quiescent current for efficiency-sensitive designs. The PDIP-8 package dictates through-hole assembly constraints compared to surface-mount alternatives.
