Overview
The MAX4427CPA+ is a dual high-speed, low-side MOSFET gate driver manufactured by Analog Devices Inc. (Maxim Integrated). It operates with a supply voltage range of 4.5V to 18V and delivers a peak output current of 1.5A for both sourcing and sinking. The device features non-inverting inputs and supports input logic levels of 0.8V (VIL) and 2.4V (VIH). Typical rise and fall times are 20ns each. It is housed in an 8-pin PDIP package with a pitch of 0.300 inches (7.62mm) and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Provides dual independent low-side drive capability with 1.5A peak output current
- Features short propagation delay times of 10ns and 25ns for enhanced switching speed
- Offers lower on-resistance compared to previous TSC series generations
Applications
- Industrial motor control systems
- Automotive power management circuits
- Aerospace electronic units
Procurement Notes
Verify the specific suffix 'CPA+' confirms the 8-PDIP through-hole package variant. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated. Ensure the component status is active. Cross-reference the datasheet for exact thermal and electrical limits before integration.
Selection Notes
Select this component for applications requiring dual low-side driving with fast switching speeds. The 1.5A current rating suits medium-power MOSFETs. The non-inverting logic simplifies control interface design. Consider the PDIP package for prototyping or through-hole manufacturing requirements.
Part Context
This part serves as an upgrade to the TSC4426/TSC4427/TSC4428 series. It improves performance by reducing on-resistance from 7Ω to 4Ω and decreasing delay times significantly. It maintains compatibility with standard MOSFET gate drive requirements while offering faster response characteristics.
Replacement Considerations
Public confirmed substitute part numbers include TSC4426, TSC4427, and TSC4428. Verify pinout and electrical specifications match before substitution.
FAQ
