Overview
The LT1158IN#PBF is a half-bridge N-channel power MOSFET gate driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 5 V to 30 V and supports input voltages up to 36 V. The device provides a peak output current of 500 mA with rise and fall times of 130 ns and 120 ns, respectively. It features both inverting and non-inverting outputs, consumes 13 mA of operating supply current, and is housed in a 16-pin PDIP package suitable for through-hole mounting.
Feature Summary
- Provides complementary high-side and low-side drive signals via dedicated inverting and non-inverting outputs
- Capable of sourcing and sinking 500 mA peak current to rapidly switch external N-channel MOSFETs
- Operates from a single supply voltage ranging from 5 V to 30 V
Applications
- Synchronous buck switching regulators
- High-efficiency DC-to-DC converters
- Half-bridge power stages
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the 16-DIP package dimensions match your PCB footprint requirements. Ensure the operating junction temperature range aligns with your thermal design constraints. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when driving N-channel MOSFETs in half-bridge configurations requiring distinct phase control. The availability of separate inverting and non-inverting outputs simplifies logic interface design compared to drivers requiring external inversion. Consider the 500 mA drive strength for moderate-speed switching applications where lower gate charge is acceptable.
Part Context
This component belongs to the LT1158 series of half-bridge drivers designed for efficient power conversion. It serves as a specialized interface between low-voltage logic controllers and high-power switching elements. The device integrates level shifting and protection features necessary for reliable operation in synchronous rectification topologies.
Replacement Considerations
LT1158CN#PBF: Identical electrical specifications and functionality; differs only in commercial temperature rating (0°C to +70°C) versus industrial rating (-40°C to +125°C). Verify thermal requirements before substitution.
