FAN6520B Rev. 1.0.3

Electrical Specifications

VCC = 5V, and TA = 25°C using circuit in Figure 1 unless otherwise noted. The • denotes specifications which apply

over the full operating temperature range.

Notes:

1. All limits at operating temperature extremes are guaranteed by design, characterization and statistical quality

control.

2. Specifications guaranteed by design/characterization (not production tested).

3. To ensure shutdown, COMP/SD pin should be held below 400mV while sinking 6mA of current.
