Product details
Overview
EL7252CSZ-T7 from Intersil is a dual-input, dual-channel high-speed power MOSFET driver IC designed for driving N- and P-channel MOSFETs in bridge configurations. It delivers 2A peak source/sink current, 20ns typical propagation delay, and operates from 4.5V to 16V supply voltage - enabling robust gate drive in switch-mode power supplies and motor control circuits.
For engineers reviewing the EL7252CSZ-T7 datasheet, EL7252CSZ-T7 pinout, EL7252CSZ-T7 application, or EL7252CSZ-T7 equivalent, key selection criteria include logic AND/NAND input compatibility, shoot-through protection capability via cross-coupling, low output impedance (3–6Ω pull-up/pull-down), and SOIC-8 packaging suitable for high-density PCB layouts.
Technical Context
The EL7252CSZ-T7 implements dual independent channel drivers with configurable 2-input logic gates (AND/NAND) per channel, supporting both non-inverted and inverted output modes. Its internal level-shifting architecture enables rail-to-rail output swing across the full 4.5V–16V V+ range while maintaining <25ns turn-on/turn-off delay at 1000pF load.
Each channel features isolated drains, hysteresis on inputs (0.3V), and integrated latching capability when cross-coupled - allowing implementation of self-resetting shoot-through protection without external logic. The device uses e3 matte tin termination and is RoHS-compliant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5V to 16V - supports wide-input industrial and automotive DC bus voltages without external regulation |
| Peak Output Current | ±2A - sufficient to rapidly charge/discharge >10nF gate capacitances at >10MHz switching frequencies |
| Propagation Delay | 20ns to 25ns - ensures tight timing alignment between dual channels for synchronous bridge control |
| Input Logic Compatibility | 3V and 5V CMOS/TTL - interoperable with microcontrollers, PWM controllers, and FPGA I/O without level shifters |
| Output Impedance | Pull-up: 3–6Ω; Pull-down: 4–6Ω - minimizes gate resistance-induced rise/fall time degradation |
| Operating Temperature | −40°C to +85°C ambient - qualified for industrial-grade thermal environments |
| Package Thermal Resistance | θJA = 95°C/W (SOIC-8) - enables 570mW max power dissipation at 85°C ambient |
Pinout & Package
EL7252CSZ-T7 is housed in an 8-lead Pb-free SOIC package (MDP0027), 3.9mm × 4.9mm body, 1.27mm pitch, with gull-wing leads and e3 matte tin finish. It is reflow-solder compatible per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A IN) | Channel A logic input A | First input for AND/NAND logic gate controlling OUT A; accepts 3V/5V logic levels |
| 2 (B IN) | Channel A logic input B | Second input for AND/NAND logic gate controlling OUT A; enables programmable enable/inhibit behavior |
| 3 (C IN) | Channel B logic input A | First input for AND/NAND logic gate controlling OUT B; electrically isolated from Channel A inputs |
| 4 (D IN) | Channel B logic input B | Second input for AND/NAND logic gate controlling OUT B; supports independent or cross-coupled control |
| 5 (V+) | Positive power supply | Primary high-side supply for both driver channels; decoupling capacitor required near pin |
| 6 (OUT A) | Channel A output | High-current push-pull output driving external N/P-MOSFET gates; isolated drain structure prevents latch-up |
| 7 (OUT B) | Channel B output | Independent high-current push-pull output; cross-coupling with OUT A enables shoot-through protection |
| 8 (GND) | Ground reference | Common return for logic inputs, supply return, and output sink paths; must be low-inductance connection |
Key Features
| Feature | Design Value |
|---|---|
| Configurable 2-input logic per channel | AND/NAND selection allows flexible enable, inhibit, and latching behavior without external gates |
| Cross-coupled shoot-through protection | Direct interconnection of OUT A→C IN and OUT B→A IN creates hardware-enforced dead-time |
| Low quiescent current | 1–2.5mA at V+ = 15V with inputs high - reduces standby power in always-on systems |
| Hysteresis on all inputs | 0.3V threshold hysteresis improves noise immunity in electrically noisy motor or SMPS environments |
| Pb-free SOIC-8 packaging | MDP0027 footprint with e3 matte tin finish - compatible with SnPb and Pb-free reflow profiles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXDN604PI | 4A peak current, 12ns delay, 8-pin PDIP only - no SOIC option; higher drive strength but larger footprint | Preferred where higher peak current (>2A) is needed for >20nF gate loads or faster switching | Select IXDN604PI when gate charge requirements exceed 40nC and layout allows PDIP placement |
| TC4427ACOA | Single-channel, 1.2A peak, 30ns delay, SOIC-8 - lacks dual-channel integration and cross-coupling logic | Requires two units and external logic for dual-channel operation; no built-in shoot-through protection | Choose TC4427ACOA only if single-channel isolation or cost sensitivity outweighs integration benefits |
Compared with IXDN604PI and TC4427ACOA, the EL7252CSZ-T7 uniquely combines dual-channel integration, AND/NAND configurability, and hardware shoot-through protection in a compact SOIC-8 package - reducing component count and PCB area while enabling safer, more deterministic bridge control.

FAQ
What logic configurations does the EL7252CSZ-T7 support per channel?
The EL7252CSZ-T7 supports AND and NAND logic configurations on each channel via its dual-input structure: A IN and B IN control OUT A, while C IN and D IN control OUT B. This allows flexible enable/inhibit behavior - for example, setting B IN high and A IN as PWM input yields non-inverted output, whereas tying B IN low forces OUT A low regardless of A IN. The EL7252CSZ-T7 datasheet confirms this behavior on page 1 and in the Timing Table.
Does the EL7252CSZ-T7 require external components for basic operation?
Yes - the EL7252CSZ-T7 requires a minimum 4.7µF bulk capacitor on V+ (pin 5) and a 0.1µF ceramic decoupling capacitor placed close to the V+/GND pins. No external pull-ups or level shifters are needed due to 3V/5V input compatibility and rail-to-rail outputs. The EL7252CSZ-T7 also needs proper ground plane routing to maintain low-inductance return paths for high di/dt currents.
Can the EL7252CSZ-T7 drive both N-channel and P-channel MOSFETs?
Yes - the EL7252CSZ-T7 is a floating-output, non-inverting/inverting dual-channel driver with isolated drains, enabling direct drive of either N-channel (low-side) or P-channel (high-side) MOSFETs. When used with external bootstrap or isolated supply, it can also drive high-side N-channel MOSFETs. The EL7252CSZ-T7's 4.5V–16V V+ range and ±2A output support both topologies without level-shifting circuitry.
What is the maximum capacitive load the EL7252CSZ-T7 can drive reliably?
The EL7252CSZ-T7 is characterized up to 10,000pF load in Figure 9 of the datasheet, with rise/fall times remaining under 100ns at V+ = 10V. For reliable operation, loads exceeding 2000pF should use optimized PCB layout (short traces, ground plane) and may benefit from series gate resistors to dampen ringing. The EL7252CSZ-T7's low 3–6Ω output impedance ensures minimal RC time constant degradation even at high capacitance.
Is the EL7252CSZ-T7 pin-compatible with the EL7242CSZ-T7?
Yes - the EL7252CSZ-T7 and EL7242CSZ-T7 share identical SOIC-8 pinouts, electrical specifications, and package dimensions (MDP0027), differing only in logic configuration: EL7242 uses OR/NOR inputs while EL7252 uses AND/NAND. This allows direct substitution in designs where logic polarity matches or can be adjusted in firmware. Both parts are listed in the same ordering table on page 2 of FN7285 Rev 5.00.
