LT1158CN#PBF

Overview

The LT1158CN#PBF is a half-bridge N-channel power MOSFET driver manufactured by Analog Devices Inc. It features two drivers with two outputs, providing an output current of 500 mA. The device operates within a supply voltage range of 5 V to 30 V and accepts input voltages between 4.5 V and 36 V. It supports both inverting and non-inverting configurations. Typical rise and fall times are 130 ns and 120 ns, respectively. The quiescent supply current is 13 mA. It is housed in a PDIP-16 package for through-hole mounting and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Provides high-current drive capability suitable for switching power MOSFETs
• Supports synchronous rectification applications to improve converter efficiency
• Offers flexible logic interface with inverting and non-inverting options

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 when sourcing. Confirm the PDIP-16 through-hole package matches the target PCB footprint. Ensure the commercial temperature range meets operational requirements. Check manufacturer documentation for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when designing synchronous rectifier circuits requiring robust gate drive for N-channel MOSFETs. The dual driver architecture simplifies half-bridge implementations compared to single-driver solutions. Consider the 500 mA peak output current against the total gate charge of the intended power switches. Verify that the 30 V maximum supply voltage aligns with the bootstrap or isolated supply design constraints.

Part Context

This part belongs to the LT1158 series of half-bridge drivers designed for power management applications. It is distinct from other Analog Devices products such as the LTC1458 DAC or LT1358 op-amp. The CN#PBF designation specifies the commercial temperature grade and lead-free packaging within the broader LT1158 family.
