Spesifikasi
IX4428NTR is a dual ultra-fast low-side MOSFET gate driver manufactured by Littelfuse (formerly IXYS IC Division). Suffix NTR stands for 8-SOIC narrow surface-mount tape-and-reel packaging for mass automated SMT production. It integrates one inverting and one non-inverting independent driver channel, delivering 1.5A peak sink/source current for high-frequency power switching topologies.
IX4428NTR SOIC8 Package
👉 It differs from IX4426 (dual inverting) and IX4427 (dual non-inverting). The mixed invert/non-invert input logic of IX4428 simplifies dead-time generation and complementary PWM drive circuits without extra logic gates, ideal for compact DC-DC converters and small motor drive boards.
Fitur Utama
- Dual Independent Driver Architecture
- Two fully isolated low-side output channels: 1 inverting input + 1 non-inverting input
- Peak output drive capacity: 1.5A source / 1.5A sink per channel
- Low output impedance: 8Ω pull-up / 4Ω pull-down for fast gate charge/discharge
- Matched ultra-fast rise/fall time (Typ 10ns / 8ns) to minimize switching dead-band loss
- Wide Supply & Robust Input Protection
- Operating supply voltage range: 4.5V ~ 35V, compatible with 12V/24V industrial power rails
- TTL/CMOS compatible logic inputs; inputs withstand negative voltage swing up to -5V to suppress ground bounce noise
- Low quiescent supply current (2.5mA typical) for light-load power saving
- Full latch-up immunity, resistant to ±1.5A transient reverse current surges
- Timing & High-Switching Performance
- Low propagation delay: 35ns typical for both turn-on and turn-off paths
- Capable of driving large gate capacitance loads up to 1nF with sub-25ns switching speed
- Minimal channel-to-channel timing skew, stable for synchronized complementary MOSFET drive
- Package & Environmental Specifications
- Package: 8-pin narrow SOIC (3.9mm width), surface mount only
- Operating temperature grade: Industrial -40°C ~ +125°C continuous operation
- MSL 3 moisture sensitivity level, fully RoHS lead-free compliant
- Tape-and-reel (TR) bulk packaging with 2000 units per reel for mass production lines
