LTC1154CN8

Overview

The LTC1154CN8 is a single high-side micropower MOSFET gate driver manufactured by Analog Devices Inc. It is designed to fully enhance N-channel power MOSFETs in high-side switching applications, eliminating the need for expensive P-channel devices. The component operates with an input voltage range up to 22 V and is housed in an 8-pin PDIP package. It integrates an internal charge pump to generate the necessary drive voltage for the external MOSFET gate.

Feature Summary

Enables the use of low-cost N-channel FETs for high-side switching applications
Integrates an internal charge pump to drive the gate voltage
Designed for micropower operation to minimize quiescent current consumption

Applications

High-side switching circuits using N-channel MOSFETs
Battery-powered systems requiring low standby current
Automotive load switching applications

Procurement Notes

Verify the specific suffix CN8 to confirm the PDIP-8 through-hole package configuration. Confirm RoHS compliance status as distributor records may vary. Check lifecycle status as this component may be discontinued or subject to limited supply constraints. Ensure the application circuit supports the internal charge pump requirements for proper MOSFET enhancement.

Selection Notes

Select this component when a single-channel high-side driver is required for N-channel MOSFETs. Consider the LTC1155 if dual channels are needed, or the LTC1156 for quad channel configurations. Verify that the input logic levels are compatible with the control source. Ensure the PCB layout accommodates the PDIP-8 package dimensions and thermal requirements for the intended switching frequency.

Part Context

The LTC1154 belongs to the Linear Technology (now Analog Devices) family of high-side MOSFET drivers. It serves as a single-channel counterpart to the dual-channel LTC1155 and the quad-channel LTC1156. These devices share the common design philosophy of enabling cost-effective N-channel solutions for high-side loads where P-channel alternatives are less efficient or more expensive.
