TMP05BKSZ-REEL7

TMP05BKSZ-REEL7 is a monolithic temperature sensor that generate a modulated serial digital output (PWM), which varies in direct proportion to the temperature of the devices. The high period (TH) of the PWM remains static over all temperatures, while the low period (TL) varies. The digital output of the device is CMOS-/TTL-compatible and is easily interfaced to the serial inputs of most popular microprocessors. It has three modes of operation: continuously converting mode, daisy-chain mode, and one shot mode. A three-state FUNC input determines the mode in which the TMP05 operate. The CONV/IN input pin is used to determine the rate at which the device measure temperature in continuously converting mode and one shot mode. In daisy-chain mode, the CONV/IN pin operates as the input to the daisy chain. It is used in applications such as isolated sensors, environmental control systems, computer thermal monitoring, thermal protection, industrial process control, power-system monitors.
