MIC5014BM

Overview

The MIC5014BM is a dual monolithic high-side and low-side MOSFET gate driver optimized for high-speed and low-voltage operations. It operates within a voltage range of 2.75V to 30V, featuring an internal charge pump for efficient high-side driving. The device draws a maximum supply current of 100µA at a 5V supply and exhibits a typical off-state current of 15µA. Designed for surface mount applications, it is housed in an 8-SOIC package with a width of 3.90mm. The component supports non-inverting input logic and functions reliably across a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrated internal charge pump enables efficient high-side MOSFET driving without external bootstrap components.
• Low quiescent current consumption ensures minimal power loss during standby and active states.
• Wide operating voltage range accommodates various low-voltage system architectures.

Applications

• High-side and low-side MOSFET switching control
• Low-voltage motor drive circuits
• Battery-powered equipment requiring low standby current

Procurement Notes

Verify the specific suffix (e.g., TR) against the required reel quantity if tape-and-reel packaging is needed. Confirm the manufacturer designation as Microchip Technology, noting prior Micrel branding in legacy documentation. Ensure the 8-SOIC package dimensions match the PCB footprint requirements. Check for discontinued status or lifecycle notices on official distributor channels before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel driver with integrated charge pump is required for low-voltage applications. The wide operating temperature range suits industrial environments. Verify that the non-inverting input configuration aligns with the control logic. Consider the low supply current for battery-operated designs where efficiency is critical.

Part Context

This part belongs to the MIC5014/5015 series of gate drivers. It serves as a cost-effective solution for driving power MOSFETs in H-bridge or half-bridge configurations. The device integrates protection features and drive capabilities typically found in discrete solutions, simplifying circuit design while maintaining performance in compact form factors.

Replacement Considerations

Check for direct pin-compatible alternatives from Microchip's current portfolio. Verify electrical parameters such as peak output current and propagation delay against the original specifications. Ensure any substitute maintains the same 8-SOIC package and operating voltage range.

FAQ

Does the MIC5014BM require external components for high-side driving?

No, the device includes an internal charge pump, eliminating the need for external bootstrap capacitors for high-side MOSFET driving.
