Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Channels** | Dual (2 independent channels) | | **Supply Voltage (VDD)** | 4.5 V to 18 V | | **Peak Output Current** | 2.0 A (Source/Sink) | | **Rise/Fall Time** | 10 ns / 10 ns (typical) | | **Propagation Delay** | 20 ns (typical) | | **Logic Input** | TTL/CMOS Compatible | | **Package Type** | 8-Lead SOIC (Small Outline Integrated Circuit) | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Functional Components and Features * **Dual-Channel Configuration:** Provides two independent drivers in a single package, allowing for the control of two separate MOSFETs (e.g., in a half-bridge or push-pull topology). * **High-Speed Switching:** The extremely low propagation delay and fast rise/fall times minimize switching losses, making it ideal for high-frequency DC-DC converters. * **Precision Inputs:** The input thresholds are fixed, ensuring consistent performance even if the supply voltage (VDD) fluctuates. * **UVLO (Under-Voltage Lockout):** Prevents the driver from operating if the supply voltage is too low, protecting the external MOSFETs from entering a linear (and damaging) state. * **Shoot-Through Protection:** Designed with internal circuitry to minimize the risk of cross-conduction in bridge circuits. --- ### 3.
