Note: Above test circuits reflected the graphs shown on “Typical Operating Characteristics” are as follows:
1–Turn-On Rising & Turn-Off Falling Time vs. Temperature, Turn-On & Off Response, Flag Response at Chip Enable, Flag
Response (Enable into Current Limit)
2–On-State & Off-State Supply Current vs. Input Voltage/Temperature, Turn-Off Leakage Current vs. Temperature
3–On-Resistance vs. Input Voltage/Temperature
4–EN Threshold Voltage vs. Input Voltage/Temperature, Flag Delay Time vs. Input Voltage/Temperature, UVLO Threshold
vs. Temperature, UVLO at Rising & Falling
5–Current Limit vs. Input Voltage/Temperature/RSET, Current Limit Factor vs. RSET, Short Circuit Current vs. Input Voltage,
Inrush Current Response, Soft-Start Response, Current-Limit & Short Circuit with Thermal Shutdown, Short-Circuit
Response
