Overview
The LTC1156CN#PBF is a quad high-side micro-power MOSFET driver manufactured by Analog Devices Inc. It operates from a 4.5V to 18V supply and features an internal charge pump for driving N-channel power MOSFETs. The device includes four independent drivers with non-inverting logic inputs. Key electrical parameters include a maximum operating temperature of +70°C, a minimum operating temperature of 0°C, and a standby current of 16µA. The package type is 16-PDIP.
Feature Summary
- Integrates an internal charge pump to drive high-side N-channel MOSFETs without external bootstrap components
- Designed for ultra-low power consumption with dedicated sleep mode functionality
- Provides four independent high-side gate driver channels with non-inverting logic compatibility
Applications
- Battery-powered systems requiring efficient power management
- Microprocessor-controlled motor control applications
- High-side switching in low-power embedded designs
Procurement Notes
Verify the specific suffix and package variant against the official Analog Devices datasheet before ordering. Confirm availability status as distribution may vary. Ensure the selected component matches the required PDIP-16 form factor and CMOS logic interface specifications for your design.
Selection Notes
Select this component when designing battery-operated systems that require high-side switching with minimal quiescent current. The integrated charge pump simplifies layout compared to discrete solutions. Verify that the 4.5V to 18V supply range aligns with your system voltage rails and that the 16-PDIP package fits your PCB constraints.
Part Context
This part belongs to the LTC1156 series of micropower MOSFET drivers. It is distinct from the LTC1155, which offers only two drivers, and the LTC1156CSW, which uses a SOIC-16 surface mount package instead of the through-hole PDIP-16 configuration found in the CN variant.
Replacement Considerations
The LTC1156CSW#PBF serves as a pin-compatible surface mount alternative within the same family. For dual-channel requirements, the LTC1155 series may be considered if fewer drivers are sufficient.
