Renesas EL7242CSZ-T13

Overview

EL7242CSZ-T13 from Intersil is a dual-input, dual-channel high-speed power MOSFET driver in an 8-lead SOIC package, delivering 2A peak source/sink current, 20ns typical propagation delay, and 4.5V–16V operating voltage - designed for shoot-through protected half-bridge gate drive in switch-mode power supplies.

For engineers reviewing the EL7242CSZ-T13 datasheet, EL7242CSZ-T13 pinout, EL7242CSZ-T13 application, or EL7242CSZ-T13 equivalent, key selection criteria include logic AND/NAND input compatibility, isolated-drain architecture for cross-coupled latching, and 10MHz clocking capability with low output impedance under capacitive loads.

Technical Context

The EL7242CSZ-T13 implements dual independent high-speed drivers with separate AND/NAND logic inputs per channel, enabling flexible configuration for synchronous rectification, shoot-through prevention, and latched protection circuits. Its internal level-shifting buffers support 3V/5V logic interfacing while maintaining rail-to-rail output swing across the full 4.5V–16V supply range.

Each channel features matched pull-up (3–6Ω) and pull-down (4–6Ω) output impedances, enabling fast rise/fall times (10ns @ 500pF) and precise timing control. The device integrates hysteresis (0.3V) on all inputs and operates reliably from –40°C to +85°C ambient with 125°C max junction temperature.

FAQ

What logic configurations does the EL7242CSZ-T13 support?

The EL7242CSZ-T13 supports both AND and NAND logic configurations per channel via its dual-input architecture (A IN/B IN for Channel A; C IN/D IN for Channel B). This allows flexible implementation of enable functions, polarity inversion, and hardware interlocks without external logic gates. Each input includes 0.3V hysteresis for noise immunity. The EL7242CSZ-T13 datasheet confirms this behavior in the Functional Description and Timing Table sections.

Can the EL7242CSZ-T13 drive both high-side and low-side N-channel MOSFETs in a half-bridge?

Yes, the EL7242CSZ-T13 can drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration. Its dual-channel, isolated-drain architecture and 4.5V–16V supply range support bootstrap or floating high-side gate drive when paired with appropriate level-shifting circuitry. The EL7242CSZ-T13's 2A peak current and 20ns propagation delay ensure fast, synchronized switching critical for efficiency and thermal management.

Does the EL7242CSZ-T13 include built-in shoot-through protection?

The EL7242CSZ-T13 does not include automatic shoot-through protection, but enables hardware-implemented protection via cross-coupling: connecting OUT B to A IN and OUT A to B IN creates a latched interlock that prevents simultaneous conduction. This method is explicitly documented in the EL7242CSZ-T13 datasheet as a standard application technique for "shoot-thru protection" and "latching drivers."

What is the maximum capacitive load the EL7242CSZ-T13 can drive reliably?

The EL7242CSZ-T13 is characterized to drive up to 1000pF loads with 10–20ns rise/fall times and maintains stable operation with larger loads (e.g., 5000pF) at reduced edge rates. The EL7242CSZ-T13's low output impedance (3–6Ω pull-up, 4–6Ω pull-down) and 2A peak current allow reliable switching into gate capacitances exceeding 5nF when used with appropriate PCB layout and decoupling. Performance curves on page 6 confirm t_R/t_F ≤100ns at 10,000pF.

Is the EL7242CSZ-T13 RoHS compliant and lead-free?

Yes, the EL7242CSZ-T13 is RoHS compliant and lead-free. Per the FN7285 Rev 5.00 datasheet, it uses 100% matte tin (e3) termination finish and Pb-free molding compounds, qualified for reflow soldering per IPC/JEDEC J-STD-020. The "CSZ" suffix explicitly denotes the Pb-free SOIC package, and the ordering table confirms EL7242CSZ-T13 is supplied in 8-lead SOIC (MDP0027) with RoHS compliance.
