Product details
Overview
The MAX6338OUB+TG069 from Maxim Integrated is a quad voltage monitor IC designed to supervise four independent power rails-specifically +5.0V, +3.3V, adjustable (via resistor divider), and -5.0V-with factory-trimmed thresholds and 10% supply tolerance. It features open-drain active-low outputs, consumes 25µA typical supply current, operates from +2.5V to +5.5V, and guarantees performance across -40°C to +85°C. It is used in multivoltage systems such as telecom infrastructure and industrial controllers where reliable, component-free power-good monitoring is required.
For engineers reviewing the MAX6338OUB+TG069 datasheet, MAX6338OUB+TG069 pinout, MAX6338OUB+TG069 application, or MAX6338OUB+TG069 equivalent, key selection considerations include its fixed +5.0V/+3.3V/-5.0V input configuration with adjustable third input, 10-pin µMAX package footprint, guaranteed temperature stability, internal bandgap reference, and wire-ORable open-drain outputs for consolidated power-good signaling.
Technical Context
The MAX6338OUB+TG069 implements four independent comparators, each comparing an input voltage against a precision internal 1.23V bandgap reference-either directly (for -5.0V via inverting configuration) or through factory-laser-trimmed resistive dividers (for +5.0V, +3.3V, and adjustable inputs). Threshold hysteresis is built-in at 0.3%, eliminating external feedback components.
All four outputs are open-drain with weak 10µA internal pull-ups to VCC, enabling direct wire-OR connection without external logic. An undervoltage lockout circuit disables all outputs when VCC drops below +2.5V, ensuring deterministic behavior during brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - supports direct connection to monitored +3.3V or +5.0V rails without level-shifting. |
| Supply Current (typ) | 25µA at +5V - enables use in always-on supervisory circuits with minimal impact on system standby power. |
| Input Thresholds | +5.0V (-10%), +3.3V (-10%), adjustable (1.23V ref), -5.0V (+10%) - matches common rail tolerances and negative bias requirements. |
| Output Type | Four independent open-drain, active-low outputs - allows flexible logic interfacing and wire-OR for single "power good" assertion. |
| Temp Range | -40°C to +85°C - fully specified for industrial and telecom environments without derating. |
| Threshold Accuracy | ±1.5% over temp - ensured by laser-trimmed dividers and 60ppm/°C bandgap reference, reducing need for calibration. |
| Propagation Delay | 20µs max - provides fast fault response while avoiding noise-induced false triggers. |
Pinout & Package
The MAX6338OUB+TG069 is housed in a 10-pin µMAX® package (3.0mm × 3.0mm, 0.6mm height, 0.5mm pitch), compatible with standard surface-mount assembly processes and offering high-density integration in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | +5.0V input | Monitors nominal +5.0V rail with -10% trip threshold (4.25V–4.50V); high-impedance node. |
| 2 (IN2) | +3.3V input | Monitors nominal +3.3V rail with -10% trip threshold (2.85V–3.00V); high-impedance node. |
| 3 (IN3) | Adjustable input | Accepts user-defined threshold via external resistor divider referenced to 1.23V internal bandgap. |
| 4 (IN4) | -5.0V input | Monitors negative rail with +10% trip threshold (-4.5V to -4.25V); uses inverting comparator architecture. |
| 5 (GND) | Analog/digital ground | Common reference for all inputs, outputs, and internal bandgap; must be low-impedance connection. |
| 6 (OUT4) | Active-low output | Asserts low when IN4 falls below -4.5V; open-drain, 10µA internal pull-up to VCC. |
| 7 (OUT3) | Active-low output | Asserts low when IN3 falls below user-set threshold; open-drain, 10µA internal pull-up to VCC. |
| 8 (OUT2) | Active-low output | Asserts low when IN2 falls below 2.85V; open-drain, 10µA internal pull-up to VCC. |
| 9 (OUT1) | Active-low output | Asserts low when IN1 falls below 4.25V; open-drain, 10µA internal pull-up to VCC. |
| 10 (VCC) | Power supply | +2.5V to +5.5V supply input; powers internal circuitry and sources internal pull-ups; includes UVLO. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed quad monitoring | Fixed +5.0V, +3.3V, adjustable, and -5.0V inputs eliminate design-time resistor selection and layout for standard rails. |
| Built-in 0.3% hysteresis | Prevents output oscillation near threshold without external feedback resistors, simplifying BOM and layout. |
| Internal 1.23V bandgap reference | Ensures stable, temperature-compensated trip points across -40°C to +85°C without external references. |
| Wire-ORable open-drain outputs | Enables aggregation of four power-good signals into one system-level "all-rails-ok" indicator using a single external pull-up. |
| Undervoltage lockout (UVLO) | Forces all outputs low when VCC < +2.5V, preventing undefined behavior during power ramp-up or brownout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6339OUB+TG069 | Same pinout and package; differs only in supply tolerance (5% vs. 10% on +5.0V and +3.3V inputs). | Used where tighter rail tolerance (e.g., +5.0V ±5%) is mandated by system spec or safety certification. | Select MAX6339OUB+TG069 when higher accuracy on primary rails is required; otherwise MAX6338OUB+TG069 offers broader margin for aging or ripple. |
| TPS3307-33DGNR | Triple monitor (not quad); +3.3V, +5.0V, and adjustable inputs only; no -5.0V support; different pinout and package (8-pin MSOP). | Suitable for systems omitting negative rail supervision or requiring lower channel count. | Choose TPS3307-33DGNR only if -5.0V monitoring is unnecessary and PCB layout allows 8-pin MSOP footprint change. |
Compared with MAX6339OUB+TG069 and TPS3307-33DGNR, the MAX6338OUB+TG069 uniquely combines quad-channel supervision, integrated -5.0V detection, 10% tolerance flexibility, and µMAX packaging-making it optimal for compact, multirail industrial and telecom systems requiring full-rail visibility without redesign.

FAQ
What input voltages does the MAX6338OUB+TG069 monitor?
The MAX6338OUB+TG069 monitors four specific inputs: nominal +5.0V (with -10% trip), +3.3V (with -10% trip), an adjustable voltage set via external resistor divider (referenced to 1.23V), and -5.0V (with +10% trip). These are factory-configured and cannot be altered post-manufacture. The MAX6338OUB+TG069 does not support other combinations such as +2.5V or +1.8V on IN3 or IN4.
Does the MAX6338OUB+TG069 require external components for basic operation?
No, the MAX6338OUB+TG069 requires no external components for monitoring its factory-programmed +5.0V, +3.3V, and -5.0V inputs. Only the adjustable input (IN3) needs two external resistors to set its threshold. A 0.1µF bypass capacitor on VCC is recommended but not mandatory for noise immunity in benign environments.
How are the outputs of the MAX6338OUB+TG069 configured and interfaced?
All four outputs (OUT1–OUT4) of the MAX6338OUB+TG069 are open-drain, active-low, and feature weak 10µA internal pull-ups to VCC. They can be directly wire-ORed using a single external pull-up resistor to any logic-compatible voltage (0V to +5.5V), enabling consolidated "power good" signaling without additional logic gates or level shifters.
What is the role of the internal bandgap reference in the MAX6338OUB+TG069?
The MAX6338OUB+TG069 uses an internal 1.23V bandgap reference to generate all input thresholds-either directly (for adjustable and -5.0V inputs) or via factory-trimmed resistor dividers (for +5.0V and +3.3V). This ensures ±1.5% threshold accuracy over -40°C to +85°C and eliminates dependency on external references or trimming components.
Can the MAX6338OUB+TG069 operate with a supply voltage below +2.5V?
No-the MAX6338OUB+TG069 incorporates an undervoltage lockout (UVLO) circuit that forces all outputs low when VCC drops below +2.5V. Operation is only guaranteed within +2.5V to +5.5V. Below +2.5V, the device ceases functional monitoring and enters a known-safe state, preventing spurious resets or undefined output behavior.
