MCP1402T-E/OT

Overview

The MCP1402T-E/OT is a single-channel, low-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 500 mA. The device features non-inverting logic compatibility with CMOS and TTL inputs. Key timing parameters include a rise time of 19 ns and a fall time of 15 ns. It functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in a compact SOT-23-5 surface-mount package and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Provides high-speed switching capabilities with nanosecond-level rise and fall times for efficient power management.
• Delivers robust 500 mA peak drive current to effectively control external power MOSFETs.
• Ensures operational reliability in harsh environments through an extended industrial temperature rating and automotive qualification.

Applications

• Automotive power distribution systems
• Industrial motor control circuits
• DC-DC converter topologies

Procurement Notes

Verify the specific suffix 'E/OT' corresponds to the required operating temperature range and tape-and-reel packaging configuration. Confirm that the AEC-Q100 qualification status aligns with your system's automotive or industrial reliability requirements. Ensure input logic levels are compatible with the specified CMOS and TTL thresholds before integration.

Selection Notes

Select this component when a compact, single-channel solution is required for driving low-side N-channel MOSFETs. The SOT-23-5 package is suitable for space-constrained designs. Consider the 500 mA drive capability against the gate charge requirements of the target MOSFET to ensure adequate switching performance without excessive heat dissipation.

Part Context

This part belongs to the MCP1401/02 series of tiny, high-speed power MOSFET drivers. These devices are designed to replace discrete driver solutions, offering reduced board space and improved performance. The series supports various packages, including SOT-23 and MSOP, catering to different density and pin-count needs.

Replacement Considerations

Direct substitutes may include other single-channel low-side drivers with similar 500 mA output current and SOT-23-5 packaging. Verify pinout compatibility and electrical specifications such as propagation delay and supply voltage range before substitution.
