Searching for a Reliable UCC27524 Alternative? Discover Slkor's High-Performance SL27524 Gate Driver!

 Slkor introduces the SL27524, a high-performance alternative to Texas Instruments’ UCC27524 — a 24V single-channel low-side gate driver designed for fast switching, reliable operation, and seamless integration into your existing designs.

Specifications:

• Supply Voltage (VDD): 24V
• Peak Output Current (IO): 4A
• Quiescent Current (IDDQ): 180μA
• Operating Temperature Range (TA): -40°C to +125°C
• Package: SOP-8

Description
 The SL27523/4/5 series are dual, 4A high-speed low-side gate drivers, designed for efficient and reliable control of MOSFETs and IGBTs. With ultra-low propagation delay and minimal channel mismatch, these drivers enable MOSFET switching frequencies up to several hundred kHz — all in a compact SOP-8 package. They’re especially well-suited for synchronous rectification in server, telecom, and high-efficiency power supply applications, where precise dead-time control directly impacts transformer converter efficiency. The driver’s two channels can be connected in parallel to boost drive current capability when needed.

Key highlights:

• Wide VDD supply range: 4.5V to 20V, ideal for driving both MOSFET and GaN power devices.
• Integrated UVLO protection: Ensures safe operation by keeping outputs low during abnormal conditions.
• Broad input voltage tolerance: -5V to +24V independent input pin range effectively handles voltage overshoots from parasitic inductance, guaranteeing stable operation.
• TTL-level compatible input thresholds for easy system integration.

Perfect for demanding applications requiring fast, efficient, and reliable power device switching.

Applications

• AC/DC and DC/DC converters
• Server power supplies and rectifiers for telecom equipment
• EV/HEV inverters and DC/DC converters
• Photovoltaic (PV) boost converters and inverters
• Uninterruptible Power Supplies (UPS)
• Motor control systems
• Ideal gate drivers for emerging wide bandgap power devices (SiC, GaN)

Key Features

• Dual-channel, independent gate driving
• 4A peak source and sink current capability
• Wide VDD operating range up to 25V
• Independent enable inputs for flexible control
• Parallel channel operation for higher drive currents
• Optional inverting and non-inverting input configurations
• VDD undervoltage lockout (UVLO) protection
• Compatible with both TTL and CMOS logic levels
• Ultra-low propagation delay for high-speed switching
• Tight delay matching (typical 1ns) between channels for synchronized performance
• Output defaults to low when input is floating for enhanced safety
• Reliable operation across a wide temperature range: -40°C to +125°C
