Product details
Overview
MAX932ESA+TG002 from Maxim Integrated is a dual micropower comparator with integrated 1.182V ±2% bandgap reference, programmable hysteresis via HYST pin, TTL/CMOS-compatible outputs sourcing up to 40mA, and operation from +2.5V to +11V single supply (or ±1.25V to ±5.5V dual supply). It targets battery-powered threshold detection and window comparator circuits where ultra-low quiescent current (<4µA over temperature) and rail-to-rail input range (V− to V+ −1.3V) are critical.
For engineers reviewing the MAX932ESA+TG002 datasheet, MAX932ESA+TG002 pinout, MAX932ESA+TG002 application, or MAX932ESA+TG002 equivalent, key selection considerations include its dual-comparator architecture with shared reference and hysteresis control, guaranteed performance from −40°C to +85°C, µMAX-8 package footprint, and compatibility with low-voltage 3V systems while maintaining 12µs propagation delay at 10mV overdrive.
Technical Context
The MAX932ESA+TG002 implements two independent comparators in an 8-pin µMAX package, each with inputs referenced to V− and outputs swinging from V+ to V−. Its internal 1.182V reference is tied to V− (not GND), enabling true dual-supply operation without ground reference constraints.
Hysteresis is implemented via the HYST pin, accepting voltage from REF down to REF −50mV; connecting external resistors between REF–HYST–V− sets symmetric threshold offsets. The output stage eliminates crowbar current during transitions, suppressing supply-induced parasitic feedback and improving layout tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +11V single supply or ±1.25V to ±5.5V dual supply - supports both battery-powered 3V systems and industrial ±5V rails. |
| Quiescent Current | <4µA over −40°C to +85°C - enables multi-year operation on coin-cell batteries in always-on monitoring. |
| Reference Voltage | 1.182V ±2% (0°C to +70°C), referenced to V− - provides stable trip point without external precision reference. |
| Propagation Delay | 12µs at 10mV overdrive - ensures timely response in oscillator and alarm timing circuits. |
| Input Common-Mode Range | V− to V+ −1.3V - allows direct sensing of signals near negative rail, e.g., current-sense amplifiers or sensor bridges. |
| Output Drive | Sources ≥40mA continuously, sinks ≥5mA - directly drives LEDs, small relays, or logic inputs without external buffers. |
| Operating Temperature | −40°C to +85°C - qualified for automotive under-hood and industrial control environments. |
Pinout & Package
MAX932ESA+TG002 is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), pin-compatible with SO-8 and DIP-8 footprints but with reduced board area. Thermal resistance θJA = 244°C/W; maximum power dissipation at +70°C ambient is 330mW.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Comparator A output; sinks and sources current; swings V+ to V− - drives TTL/CMOS loads directly when V− = GND. |
| 2 | V− | Negative supply terminal; connect to GND for single-supply operation - defines reference for REF and input common-mode range. |
| 3 | INA+ | Noninverting input of comparator A - accepts signals from V− to V+ −1.3V; high-impedance (±0.01nA leakage). |
| 4 | INB− | Inverting input of comparator B - matched offset and leakage to INA+; enables differential or window configurations. |
| 5 | INB+ | Noninverting input of comparator B - identical electrical specs to INA+, supporting dual independent thresholds. |
| 6 | REF | 1.182V ±2% reference output referenced to V− - supplies hysteresis network and external circuitry; max load ±8µA sink / +15µA source. |
| 7 | V+ | Positive supply input - accepts up to +11V; powers comparators, reference, and output stage. |
| 8 | HYST | Hysteresis control input - voltage set between REF and REF −50mV determines hysteresis band width (up to 100mV). |
Key Features
| Feature | Design Value |
|---|---|
| No crowbar switching current | Eliminates supply rail glitches during output transitions, reducing need for aggressive bypassing and improving stability in noisy layouts. |
| Programmable hysteresis via HYST pin | Enables precise, resistor-set hysteresis without external feedback networks - simplifies design and reduces component count vs. discrete solutions. |
| Rail-to-rail input range | Supports sensing from V− to within 1.3V of V+, enabling direct interface with current-sense amps, thermocouples, and low-side shunt monitors. |
| 40mA continuous output source | Drives LEDs, small solenoids, or logic gates directly - avoids external driver stages in portable instrumentation and alarm indicators. |
| Internal 1.182V ±2% reference | Provides stable, temperature-compensated threshold without external components - reduces BOM cost and PCB area in battery-critical designs. |
Applications
| Battery-Powered Threshold Detector | Window Comparator for Power Monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator with reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX932CSA | Same functionality and pinout, but rated for 0°C to +70°C commercial temperature range - lacks extended −40°C to +85°C qualification. | Not suitable for automotive or outdoor industrial deployments requiring full industrial temp range. | Select MAX932CSA only for cost-sensitive consumer-grade products operating in controlled environments. |
| MAX922ESA | Pin-incompatible dual comparator with 1% reference (vs. 2%); higher supply current (6µA typical); no HYST pin - requires external hysteresis network. | Delivers tighter threshold accuracy but increases design complexity and board area for hysteresis implementation. | Choose MAX922ESA when absolute threshold precision outweighs layout simplicity and ultra-low power requirements. |
Compared with MAX932CSA, MAX932ESA+TG002 offers guaranteed operation down to −40°C and tighter thermal drift control; compared with MAX922ESA, it trades 1% reference accuracy for integrated hysteresis, 2µA lower quiescent current, and simplified PCB layout - making it optimal for ruggedized, battery-constrained systems.

FAQ
What is the operating temperature range of the MAX932ESA+TG002?
The MAX932ESA+TG002 is specified for −40°C to +85°C operation, validated across this full industrial temperature range per its datasheet. This makes MAX932ESA+TG002 suitable for under-hood automotive sensors, outdoor IoT nodes, and factory-floor controllers where ambient temperatures exceed commercial-grade limits.
Can the MAX932ESA+TG002 operate from a 3V single supply?
Yes, the MAX932ESA+TG002 operates from +2.5V to +11V single supply, including 3V systems. At 3V, it maintains <4µA quiescent current, 1.182V reference accuracy, and 14µs propagation delay - confirmed in the Electrical Characteristics tables for 3V operation. MAX932ESA+TG002 delivers reliable performance in coin-cell and Li-ion powered devices.
How is hysteresis configured on the MAX932ESA+TG002?
Hysteresis on the MAX932ESA+TG002 is set via the HYST pin: connect R1 between REF and HYST, and R2 between HYST and V−. The hysteresis band equals twice (REF − VHYST), adjustable up to 100mV. This method requires no external op-amps or feedback paths - a key differentiator of MAX932ESA+TG002 versus standard comparators.
What is the output swing capability of the MAX932ESA+TG002?
The MAX932ESA+TG002 outputs swing from V+ to V−, supporting true dual-supply operation. When V− = GND, outputs swing rail-to-rail (e.g., 0V to 5V). Each output sources ≥40mA continuously and sinks ≥5mA - enabling direct drive of LEDs, logic inputs, or small MOSFET gates without external buffers. This is explicitly verified in the "Output High/Low Voltage" and "Source/Sink Current" specs.
Is the internal reference of the MAX932ESA+TG002 referenced to GND or V−?
The internal 1.182V reference of the MAX932ESA+TG002 is referenced to V−, not GND. This allows correct operation in dual-supply configurations (e.g., ±5V) where V− = −5V and REF = −3.818V. Designers must reference all HYST and threshold networks to V− - a critical detail confirmed in the "Voltage Reference" section and pin descriptions of the MAX932ESA+TG002 datasheet.
