The device features ultra-low R ON of 0.8Ω (maximum) at 4.5V and operates over the wide range of 1.65V to 5.5V. The device is fabricated with sub-micron CMO technology to achieve fast switching speeds and is designed for break-before-make operation. The F2859 interfaces between the low-voltage IC and regular audio amplifiers and CODECs operating up to the supply range of 5.5V through the dual-voltage supplies of V IO and. The V IO supply operates the control circuitry, allowing for 1.8V (typical) signals on the control pin (n).

bsolute Maximum Ratings tresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. ymbol Parameter Min. Max.
