Product details
Overview
TMP01FPZ from Analog Devices is a programmable temperature controller IC with dual open-collector outputs (OVER/UNDER), ±1.0°C typical accuracy over −55°C to +125°C, 5 mV/K VPTAT output, and user-programmable trip points via external resistors. It functions as a self-contained thermostatic control element in thermal protection circuits, HVAC sensor interfaces, and industrial process monitoring systems.
For engineers reviewing the TMP01FPZ datasheet, TMP01FPZ pinout, TMP01FPZ application, or TMP01FPZ equivalent, key selection criteria include its 20 mA sink capability per output, 4.5 V to 13.2 V single-supply operation, 500 μA max quiescent current at 5 V, and compatibility with TTL/CMOS logic levels - all critical for board-level thermal alarm design and relay-driven thermal shutdown.
Technical Context
The TMP01FPZ integrates a precision band gap voltage reference (2.5 V ±10 mV) and a matched pair of comparators that monitor VPTAT against externally set high/low thresholds. Its hysteresis is generated by mirroring the VREF load current (7 μA base + 5 μA/°C scaling), enabling deterministic, non-overlapping trip zone transitions.
VPTAT exhibits a precisely trimmed 5 mV/K scale factor (1.49 V nominal at 25°C), while comparator inputs accept ground-referenced setpoint voltages derived from resistor dividers or DACs. The device operates without internal trimming components - laser-trimmed thin-film resistors ensure ±1°C accuracy across the full −55°C to +125°C range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VPTAT Scale Factor | 5 mV/K - enables direct Kelvin-to-voltage conversion; 1.49 V at 25°C (298.15 K) |
| Temperature Accuracy (F Grade) | ±1.0°C typ at 25°C; ±2.0°C max over −40°C to +85°C - supports industrial-grade thermal setpoint control |

| VREF Output | 2.500 V ±10 mV at 25°C - stable reference for accurate resistor-divider setpoint generation |
Pinout & Package
The TMP01FPZ is housed in an 8-pin plastic DIP (PDIP) package with through-hole mounting and standard 0.3-inch body width.

Equivalent & Alternatives
The following parts are listed as comparable options for similar temperature controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM56CIMX/NOPB | Fixed 25°C/40°C thresholds; no user-programmable hysteresis; 10-bit VPTAT ADC output instead of analog VPTAT | Limited to dual-point alarms only; lacks resistor-based trip point flexibility and direct 20 mA drive | Choose LM56CIMX/NOPB only if fixed thresholds suffice and digital interface is preferred over analog control. |
| MAX6505ESA+ | Single-output (OVER only); ±3°C accuracy over −40°C to +125°C; no VREF or VPTAT analog outputs | Designed for simple overtemperature cutoff only; cannot implement window-based thermostatic control | Choose MAX6505ESA+ only for cost-sensitive, single-threshold safety cutoff where analog monitoring is unnecessary. |
Compared with LM56CIMX/NOPB and MAX6505ESA+, the TMP01FPZ uniquely delivers programmable dual thresholds, analog VPTAT/VREF outputs, and 20 mA sink capability in one monolithic IC - making it the only option for hardware-based, resistor-configured thermostats requiring both over- and under-temperature action.

FAQ
What is the operating temperature range of the TMP01FPZ?
The TMP01FPZ operates from −55°C to +125°C, with guaranteed ±1.0°C typical accuracy over this full range. Its internal band gap reference and laser-trimmed thin-film resistors maintain stability across extreme conditions, making it suitable for automotive under-hood, industrial motor control, and outdoor equipment applications where ambient temperatures vary widely. The TMP01FPZ datasheet specifies performance down to −55°C and up to +125°C, with extended reliability validated to +150°C junction temperature.
How do I program the temperature trip points on the TMP01FPZ?
You program the TMP01FPZ trip points using external resistors connected between VREF, SET HIGH, SET LOW, and GND to form a three-resistor divider ladder. The VREF output (2.5 V) supplies current through R1, R2, and R3 to generate precise voltages at SET HIGH and SET LOW pins. For example, to set 60°C high and 40°C low with 2°C hysteresis, calculate VSETHIGH = (60 + 273.15) × 0.005 = 1.666 V, then determine R1 = (2.5 − 1.666)/17 μA ≈ 49 kΩ. The TMP01FPZ uses these voltages to compare against its internal VPTAT signal and assert OVER or UNDER accordingly.
Can the TMP01FPZ drive a relay directly?
Yes, the TMP01FPZ can drive small electromagnetic relays directly via its 20 mA open-collector outputs (OVER and UNDER). Each output sinks up to 20 mA at ≤0.6 V saturation voltage when loaded, sufficient for coils rated ≤250 Ω at 5 V or ≤600 Ω at 12 V. However, for higher-current loads or inductive kickback suppression, a flyback diode (e.g., IN4001) must be added across the relay coil. The TMP01FPZ's low quiescent current (500 μA) and robust output stage make it ideal for relay-based thermal cutoff without external driver transistors.
What is the purpose of the VPTAT and VREF pins on the TMP01FPZ?
The VPTAT pin outputs a voltage proportional to absolute temperature (1.49 V at 25°C, +5 mV/K slope), used for analog temperature monitoring or feedback loops. The VREF pin delivers a stable 2.500 V ±10 mV reference, serving two roles: (1) generating precise setpoint voltages for SET HIGH/SET LOW via resistor dividers, and (2) defining hysteresis magnitude via its load current (IHYS = IVREF = 7 μA + 5 μA/°C). Both outputs are buffered and specified for accuracy across the full −55°C to +125°C range, enabling the TMP01FPZ to function as a complete analog thermal control subsystem.
Does the TMP01FPZ require external calibration?
No, the TMP01FPZ does not require external calibration. It achieves ±1.0°C typical accuracy over −55°C to +125°C using factory-laser-trimmed thin-film resistors and a precision band gap reference. All key parameters - including VPTAT scale factor (5 mV/K), VREF output (2.500 V), and comparator offset - are trimmed during production. Users only configure trip points and hysteresis via external resistors; no post-assembly adjustment or software calibration is needed. The TMP01FPZ maintains this accuracy without recalibration throughout its operational lifetime under normal conditions.
