MCP14A0151T-E/CH

Overview

The MCP14A0151T-E/CH is a single-channel 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 1.5 A for both sourcing and sinking. The device features an inverting logic input with low threshold levels (VIL: 0.8 V, VIH: 2 V). Typical propagation delays are 33 ns and 24 ns, while rise and fall times are 11.5 ns and 10 ns, respectively. It is housed in a SOT-23-6 surface-mount package and supports junction temperatures up to 150°C.

Procurement Notes

Verify the complete part number including suffixes such as -E/CH against official Microchip documentation to ensure correct temperature grade and packaging configuration. Confirm RoHS compliance status and specific tape-and-reel quantities if ordering bulk units. Cross-reference datasheet revision dates to validate electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a compact single-driver solution is required for N-channel or P-channel MOSFETs. The SOT-23-6 package suits space-constrained designs. Ensure the load capacitance does not exceed the driver's specified capacitive load drive capability to maintain signal integrity. Verify that the input logic levels match the controlling microcontroller or FPGA outputs.

Part Context

This device belongs to the MCP14A015x family of MOSFET drivers from Microchip Technology. It shares functional similarities with the MCP14A0152 variant but differs in pinout configuration and specific internal circuitry optimizations. The family targets applications requiring efficient switching with minimal quiescent current consumption in small form-factor packages.

Replacement Considerations

Direct substitutes include other single-channel MOSFET drivers with comparable 1.5 A output current and SOT-23-6 packaging. Verify pin compatibility and logical inversion requirements before substitution. Alternative parts must support the same supply voltage range and meet similar thermal performance standards.

FAQ
