What are the key features of TMP05BRTZ-REEL7?
- PWM duty-cycle output encodes temperature directly, eliminating the need for an ADC on the host microcontroller
- Typical accuracy of ±0.5°C (±1°C max) over the -40°C to +125°C operating range for precise thermal monitoring
- Daisy-chainable single-wire bus supports multiple TMP05 sensors on one GPIO line, reducing wiring in distributed sensing arrays
- Ultra-compact 5-pin SC-70 package (2.9 mm x 1.6 mm x 1.15 mm) for space-constrained PCB designs
What is TMP05BRTZ-REEL7 used for?
The TMP05BRTZ-REEL7 is used in industrial equipment thermal management where multiple temperature zones must be monitored with minimal GPIO usage. Its PWM output connects directly to a microcontroller timer input, enabling accurate temperature readback without an external ADC in battery-powered IoT nodes and HVAC controllers. Consumer electronics and IT equipment board thermal monitoring also benefit from its daisy-chain capability and compact SC-70 footprint.

Frequently Asked Questions
How does the TMP05BRTZ-REEL7 encode temperature without requiring an ADC?
The TMP05BRTZ-REEL7 outputs temperature as a PWM duty cycle: the ratio of the high-time to total period maps linearly to temperature. A host microcontroller captures two timer counts to compute temperature to better than 1°C resolution, making an external 12-bit ADC unnecessary and reducing BOM cost by several components.
Over what temperature range is the TMP05BRTZ-REEL7 rated and what accuracy can designers expect?
The sensor operates over -40°C to +125°C with a typical accuracy of ±0.5°C and a maximum error of ±1°C across the industrial range. This level of precision is sufficient for board thermal shutdown, fan speed control, and compliance with IEC 60068 thermal endurance test monitoring without factory calibration.
How many TMP05 sensors can be daisy-chained on a single microcontroller GPIO line?
The TMP05 daisy-chain architecture allows up to 8 sensors to share a single 2-wire bus (DATA and CLK), each converting sequentially and passing the CLK pulse to the next device. This reduces a multi-zone temperature monitoring system from requiring 8 GPIO inputs down to just 2 pins, freeing microcontroller I/O for other functions.
What PCB footprint does the TMP05BRTZ-REEL7 SC-70 package occupy compared to SOT-23?
The 5-pin SC-70 package body measures 2.9 mm x 1.6 mm, which is approximately 35% smaller in footprint area than a standard SOT-23-5 package. At 1.15 mm height it also clears most component clearance requirements for stacked PCB assemblies in portable and wearable designs.
