Evaluation Board
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-
free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL9492 . For more information on MSL please see techbrief TB363.

FUNCTION
Charge pump connection 1
Boost regulator sense line. Connect to boost output capacitor.
No connect pins
Analog 5V supply. Decouple with 1μF ceramic capacitor and a ferrite bead (see “ABYP” on page 14 for
more detail).
Main power supply to the chip.
This is the Drain of the Boost MOSFET. The Boost inductor will be connected to this pin.
Power gound for the Internal Boost MOSFET.
Digital 5V supply. Decouple with 1μF ceramic capacitor.
Logic combination at the ADD0 and ADD1 can select four different chip select addresses.
External control of output voltage selection.
Tone detector input.
The envelope of the actually detected external tone signal. It is an open-drain output.
