Texas Instruments TMP106YZCR

Overview

TMP106YZCR from Texas Instruments is a digital temperature sensor IC in a 6-pin DSBGA (YZC) package, featuring a two-wire SMBus-compatible interface, user-selectable 9- to 12-bit resolution (0.0625°C at 12-bit), ±2.0°C max accuracy from −25°C to +85°C, and ultra-low quiescent current of 50 µA active / 0.1 µA standby - deployed for thermal protection in battery-powered portable electronics.

For engineers reviewing the TMP106YZCR datasheet, TMP106YZCR pinout, TMP106YZCR application, or TMP106YZCR equivalent, this page delivers verified electrical specs, WCSP-6 terminal mapping, SMBus Alert functionality, resolution vs. conversion time trade-offs, and validated alternatives for thermal management designs requiring compact, low-power, I²C-compatible sensing.

Technical Context

The TMP106YZCR integrates a ΔΣ ADC, on-chip oscillator, configuration logic, and SMBus-compliant serial interface with integrated spike suppression filters and Schmitt triggers on SDA/SCL. It supports fast-mode (up to 400 kHz) and high-speed mode (up to 3.4 MHz) I²C operation, with timeout detection (54 ms typical) and programmable fault queue (1/2/4/6 consecutive faults).

Its register architecture includes a read-only 12-bit Temperature Register, configurable Configuration Register (R1/R0 for resolution, TM for thermostat mode, POL for ALERT polarity, SD for shutdown), and THIGH/TLOW limit registers - all accessed via an 8-bit pointer register with MSB-first byte ordering and no power-up sequence required.

FAQ

What is the maximum I²C clock frequency supported by the TMP106YZCR?

The TMP106YZCR supports fast-mode I²C up to 400 kHz and high-speed mode up to 3.4 MHz. High-speed operation requires the master to issue an Hs-mode master code (00001XXX) after START; the TMP106YZCR then switches its internal filters to accommodate faster edges. The TMP106YZCR remains in high-speed mode until a STOP condition is detected.

Does the TMP106YZCR require external components for basic operation?

No, the TMP106YZCR requires no external components for core functionality. Pull-up resistors on SDA, SCL, and ALERT are mandatory per I²C/SMBus specification, but the TMP106YZCR integrates all signal conditioning, reference, and conversion circuitry. A 0.1 µF bypass capacitor on V+ is recommended but not required for stable operation.

How does the ALERT pin behave in Comparator Mode versus Interrupt Mode?

In Comparator Mode (TM = 0), the ALERT pin stays active until temperature falls below TLOW for the programmed number of consecutive faults. In Interrupt Mode (TM = 1), ALERT asserts on THIGH breach and clears only upon any register read or successful SMBus Alert Response - enabling event-driven firmware handling without continuous polling of the TMP106YZCR.

Can the TMP106YZCR measure temperature accurately when mounted on a PCB with high copper pour?

Yes, but thermal conduction through PCB copper can bias readings. The TMP106YZCR senses die temperature directly; its leads provide the primary thermal path. For accurate ambient air measurement, isolate the YZC package using minimal copper connections and avoid large thermal planes beneath the device. For board temperature monitoring, direct mounting maximizes thermal coupling to the TMP106YZCR.

What happens to the TMP106YZCR's configuration registers after a power cycle?

All configuration registers (including resolution, TM, POL, SD, THIGH, TLOW) retain their last-written values across power cycles - except when reset via General Call Reset command (0000000 + 00000110), which restores THIGH = 80°C, TLOW = 75°C, and all Configuration Register bits to zero. The TMP106YZCR has no nonvolatile memory; register state is volatile but preserved during brownout if V+ remains above 1.5 V.
