TK11051

DESCRIPTION

The TK11051 is an accurate temperature controller IC for

use over the -30 to +105 °C temperature range. The

TK11051 monolithic bipolar integrated circuit contains a

temperature sensor, stable voltage reference and a

comparator, making the device very useful as an on/off

temperature controller. Two external resistors easily set

thesensingtemperaturethresholdandhysteresis. Itswide

operating voltage range of 2.7 to 6.0 V makes this IC

suitable for a number of applications requiring accurate

temperature control. The device is in the “on” state when

the control pin is pulled to a logic high level.
