Features

The ISL24212 is an 8-bit programmable current sink that can be

used in conjunction with an external voltage divider to generate a

can be controlled between any arbitrary voltage range. The

ISL24212 has an 8-bit data register and 8-bit EEPROM for storing

both a volatile and a permanent value for its output, accessible

through a single up/down counter interface pin (CTL). After the

Enable pin (CE) can be grounded to prevent further changes. On

every power-up, the EEPROM contents are automatically

transferred to the data register and the pre-programmed output

voltage appears at the VCOM_OUT pin.

The ISL24212 is available in an 10 Ld 3mm x 3mm TDFN

package. This package has a maximum height of 0.8mm for very

low profile designs. The ambient operating temperature range is

-40°C to +85°C.
