Product details
Overview
MAX792TESE+ from Maxim Integrated is a microprocessor supervisory circuit providing reset generation, manual reset input, two-stage power-fail warning, watchdog timeout detection, and chip-enable signal gating for nonvolatile memory protection. It features 200ms reset timeout, ±2% reset threshold accuracy (in external programming mode), and guaranteed RESET validity down to VCC = 1V. It is used in embedded controllers and critical µP power monitoring systems where reliable brownout and software fault recovery are required.
For engineers reviewing the MAX792TESE+ datasheet, MAX792TESE+ pinout, MAX792TESE+ application, or MAX792TESE+ equivalent, this page delivers verified functional identity, confirmed 16-pin narrow SO package mapping, validated 16-pin terminal roles, exact reset threshold (3.06V nominal), watchdog timeout configuration method, and two manufacturer-confirmed alternative parts with documented technical and application differences.
Technical Context
The MAX792TESE+ integrates independent reset and low-line comparators with factory-trimmed internal thresholds (3.06V reset, 3.18V low-line) and supports external resistor-divider programming for custom thresholds. Its watchdog timer uses an external capacitor on SWT to set timeout periods (e.g., 1.6s default with SWT = VCC; scalable via k×C formula).
It implements a bidirectional CE transmission gate with ≤10ns propagation delay and automatic write-cycle completion hold during reset assertion. The device operates across 2.75V–5.5V supply range, maintains valid RESET output down to 1V VCC, and includes overvoltage comparator (OVI/OVO) with 1.30V reference - all within a single 16-pin narrow SO package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold Voltage | 3.06V nominal (T suffix); ensures deterministic µP reset initiation at precise supply voltage level |
| Reset Timeout Period | 200ms typical; guarantees stable processor initialization after power-up or brownout recovery |
| Watchdog Timeout (default) | 1.6s with SWT tied to VCC; provides sufficient margin for normal firmware execution cycles |
| Supply Voltage Range | 2.75V to 5.5V; supports both 3.3V and 5V system rails without level-shifting |
| RESET Output Validity | Guaranteed down to VCC = 1V; enables fail-safe reset signaling even during deep brownout |
| CE Propagation Delay | ≤10ns max; preserves timing integrity for high-speed memory access in µP systems |
| Operating Temperature | 0°C to +70°C; qualified for commercial-grade industrial control and instrumentation |
Pinout & Package
MAX792TESE+ is housed in a 16-pin narrow SO (SOIC-N) package, 7.5mm × 4.4mm body, 1.27mm pitch, RoHS-compliant lead-free finish (+ suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | RESET / RESET | Complementary active-low and active-high reset outputs; drive µP reset pin directly with guaranteed logic levels down to VCC = 1V |
| 3 | VCC | Main supply input; powers all internal comparators, timers, and gating logic |
| 4 | RESET IN/INT | Mode select: grounded for internal threshold mode (3.06V), pulled ≥600mV for external resistor-divider programming |
| 5 | LLIN/REFOUT | In external mode: low-line comparator input; in internal mode: buffered 1.30V reference output |
| 6 | OVO | Open-drain overvoltage comparator output; asserts low when OVI > 1.30V, independent of other functions |
| 7 | OVI | Inverting input to uncommitted overvoltage comparator; connect to voltage divider for overvoltage detection |
| 8 | SWT | Set watchdog timeout: tie to VCC for 1.6s default; connect capacitor to GND for adjustable timeout (k×C formula) |
| 9 | MR | Manual reset input; internally pulled up, accepts TTL/CMOS logic or pushbutton switch without external components |
| 10 | LOW LINE | Active-low NMI output; asserts 120mV above reset threshold (3.18V) to warn µP before reset occurs |
| 11 | WDI | Watchdog input; requires edge transition every <1.6s to prevent WDPO/WDO assertion |
| 12 | GND | Ground reference for all analog comparators and digital logic |
| 13 | CE OUT | Chip-enable output; gated pass-through of CE IN only when reset is deasserted; holds low 15µs after reset if CE IN was low |
| 14 | CE IN | Chip-enable input; high-impedance during reset to isolate memory bus from corrupted writes |
| 15 | WDO | Watchdog output; latched low after timeout until next WDI transition; used for hardware shutdown or MR assertion |
| 16 | WDPO | Watchdog pulse output; 500µs–6ms low pulse preceding WDO by 70ns; clocks external flip-flop for two-fault shutdown |
Key Features
| Feature | Design Value |
|---|---|
| Two-stage power-fail warning | Separate LOW LINE output asserts 120mV above reset threshold, enabling preemptive NMI before system reset |
| Pulsed watchdog output (WDPO) | Provides 500µs–6ms advance warning pulse before WDO latches low, enabling two-fault shutdown architecture |
| On-board CE signal gating | Hardware-enforced isolation of chip-enable path during reset, preventing partial writes to CMOS RAM/EEPROM |
| Memory write-cycle completion | CE OUT remains low for 15µs after reset assertion if CE IN was low, ensuring ongoing memory write completes |
| Voltage monitor for overvoltage warning | Dedicated OVI/OVO comparator with 1.30V reference allows independent overvoltage detection without affecting reset behavior |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX820TESE+ | Identical pinout and function; guarantees ±2% reset/low-line threshold accuracy (vs. MAX792's typical ±2.5%) | Required where production calibration tolerance must be bounded across full temperature range | Select MAX820TESE+ when design validation mandates worst-case ±2% threshold accuracy over -40°C to +85°C |
| TPS3808G30DBVR | Single-output reset IC (RESET only); no LOW LINE, WDPO, CE gating, or OVI/OVO; 3.0V fixed threshold; 200ms timeout | Suitable only for basic reset-only use cases; lacks dual-warning, memory protection, and watchdog features | Choose TPS3808G30DBVR only if system requires minimal reset supervision without NMI, watchdog, or memory gating functionality |
Compared with MAX792TESE+, MAX820TESE+ offers tighter threshold accuracy for high-reliability deployments, while TPS3808G30DBVR reduces cost and complexity in designs that omit low-line warning, watchdog, and CE gating - but neither provides the full feature set of the MAX792TESE+ in a drop-in replacement.

FAQ
What is the nominal reset threshold voltage for MAX792TESE+?
The MAX792TESE+ has a nominal reset threshold voltage of 3.06V, corresponding to the 'T' suffix in its part number. This value is factory-trimmed and specified with ±2.5% typical accuracy over temperature. In external programming mode (using resistor dividers on RESET IN/INT and LLIN/REFOUT), the MAX792TESE+ supports custom thresholds with ±2% accuracy when referenced to the internal 1.30V bandgap.
How does the watchdog timeout period work on MAX792TESE+?
The MAX792TESE+ watchdog timeout defaults to 1.6 seconds when the SWT pin is tied to VCC. To adjust it, connect a capacitor from SWT to GND: timeout = k × C (in nF), where k = 27 for VCC = 3V and k = 16.2 for VCC = 5V. The MAX792TESE+ watchdog is disabled when VCC falls below the reset threshold, and WDO remains latched low until the next WDI transition.
Can MAX792TESE+ monitor both reset and low-line conditions simultaneously?
Yes, the MAX792TESE+ monitors both conditions concurrently. In internal threshold mode, it asserts LOW LINE at 3.18V (120mV above the 3.06V reset threshold) to provide early warning via NMI, then asserts RESET at 3.06V if VCC continues falling. This two-stage detection enables firmware to save state before hard reset, and the 15mV hysteresis on both comparators prevents chatter during slow supply ramps.
What is the purpose of the CE IN and CE OUT pins on MAX792TESE+?
The CE IN and CE OUT pins implement a hardware-controlled transmission gate that isolates the memory chip-enable signal during reset. When reset is active, CE IN becomes high-impedance and CE OUT is held low for 15µs (if CE IN was low) to complete ongoing writes. This prevents partial or corrupted writes to CMOS RAM or EEPROM during power transitions - a key reliability feature absent in basic reset ICs.
Does MAX792TESE+ support overvoltage detection?
Yes, the MAX792TESE+ includes a dedicated overvoltage comparator with OVI (input) and OVO (open-drain output). When OVI exceeds 1.30V - set by an external resistor divider - OVO pulls low. This function operates independently of reset, watchdog, and low-line circuits, allowing simultaneous monitoring of overvoltage events without interfering with core supervision logic.
