The TMP05/TMP06 are monolithic temperature sensors 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 B Grade version offers a high temperature accuracy of ±1°C from 0°C to 70°C with excellent transducer linearity. The digital output of the TMP05/ TMP06 is CMOS-/TTL-compatible and is easily interfaced to the serial inputs of most popular microprocessors. The flexible open-drain output of the TMP06 is capable of sinking 5 mA.
The TMP05/TMP06 are specified for operation at supply voltages from 3 V to 5.5 V. Operating at 3.3 V, the supply current is typically 370 μA. The TMP05/TMP06 are rated for operation over the –40°C to +150°C temperature range. It is not recommended to operate these devices at temperatures above 125°C for more than a total of 5% (5,000 hours) of the lifetime of the devices. They are packaged in low cost, low area SC-70 and SOT-23 packages.
The TMP05/TMP06 have 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/TMP06 operate.
The CONV/IN input pin is used to determine the rate at which the TMP05/TMP06 measures 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.Product Highlights
- The TMP05/TMP06 have an on-chip temperature sensor that allows an accurate measurement of the ambient temperature. The measurable temperature range is –40°C to +150°C.
- Supply voltage is 3 V to 5.5 V.
- Space-saving 5-lead SOT-23 and SC-70 packages.
- Temperature accuracy is typically ±0.5°C. Each part needs a decoupling capacitor to achieve this accuracy.
- Temperature resolution of 0.025°C.
- The TMP05/TMP06 feature a one shot mode that reduces the average power consumption to 102 μW at 1 SPS.
- Isolated sensors
- Environmental control systems
- Computer thermal monitoring
- Thermal protection
- Industrial process control
- Power-system monitors
