Product details
Overview
MAX6314US30D1+T from Maxim Integrated is a low-power CMOS microprocessor supervisory circuit designed to monitor VCC supply voltage and assert a bidirectional reset signal for µPs with compatible reset I/Os (e.g., Motorola 68HC11). It features a factory-trimmed 3.00V reset threshold, 1ms minimum reset timeout period, ±1.8% threshold accuracy at +25°C, and operates from 2.5V to 5.5V. It is used in portable/battery-powered equipment requiring reliable power-on reset and brownout protection.
For engineers reviewing the MAX6314US30D1+T datasheet, MAX6314US30D1+T pinout, MAX6314US30D1+T application, or MAX6314US30D1+T equivalent, key selection considerations include its bidirectional RESET output architecture, internal 4.7kΩ pull-up with active P-channel assist, manual reset input with 63kΩ internal pull-up, and immunity to short VCC transients - all critical for robust reset signaling in multi-device reset buses.
Technical Context
The MAX6314US30D1+T implements a precision voltage-monitoring comparator with laser-trimmed resistive divider to detect VCC falling below 3.00V ±1.8% (at +25°C), triggering a reset assertion that persists for ≥1ms after VCC recovers. Its RESET output combines an N-channel pulldown, a 4.7kΩ passive pull-up, and a P-channel active pull-up enabled for 2µs upon rising-edge detection - enabling fast rise time (<350ns typical) even under 390pF load.
It integrates a debounced manual reset input (MR) with internal 63kΩ pull-up, supporting direct switch-to-GND connection without external components. The device is immune to VCC transients ≤100µs (at 100mV overdrive), and draws only 5µA quiescent current at +25°C across its full operating range of –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.00V ±1.8% at +25°C; ensures reliable reset assertion during brownout down to nominal 3.0V rail |
| Reset Timeout Period | ≥1ms minimum; guarantees µP remains held in reset long enough for stable power recovery |
| Supply Current | 5µA typical at +25°C; enables ultra-low-power operation in battery-critical systems |
| VCC Operating Range | 2.5V to 5.5V; supports wide-input applications including 3.3V and 5V logic domains |
| MR Input Threshold | VIL = 0.8V max; allows clean logic-low detection with standard CMOS/TTL-compatible signals |
| RESET Rise Time | ≤350ns (CL = 390pF); meets timing requirements for fast µPs like 68HC11 even with multiple devices on bus |
| Tempco | 60ppm/°C; maintains tight threshold stability over –40°C to +85°C industrial temperature range |
Pinout & Package
SOT143 package: 4-pin, surface-mount, lead-free (RoHS-compliant), -40°C to +85°C operating temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply voltage input and reset threshold monitor | Monitored rail; internal laser-trimmed divider sets 3.00V trip point; must be decoupled with 0.1µF capacitor |
| MR | Manual reset input | Active-low; internally pulled up to VCC via 63kΩ resistor; asserts reset when pulled ≤0.8V |
| RESET | Bidirectional reset output | Combines N-channel sink, 4.7kΩ pull-up, and P-channel active pull-up; interfaces directly with 68HC11-style bidirectional reset pins |
| GND | Ground reference | Return path for all internal circuitry; must be connected to system ground plane with low-impedance trace |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional RESET output | Enables direct interface with µPs like 68HC11 that sense reset source (external vs. internal) by sampling RESET state post-reset |
| Integrated 4.7kΩ pull-up + P-channel assist | Reduces RESET rise time to <350ns under 390pF load, eliminating need for external pull-up and preventing false external-reset interpretation in multi-device systems |
| Factory-trimmed 3.00V threshold | Eliminates external resistor network; achieves ±1.8% accuracy at +25°C and ±2.5% over full temperature range |
| Debounced MR input | Supports direct connection of momentary switch to GND; no external RC debounce required due to internal glitch rejection (100ns) |
| 5µA supply current | Extends battery life in portable instrumentation and handheld controllers where standby current is critical |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6315US30D1+T | Open-drain RESET output (no internal pull-up or P-channel assist); identical 3.00V threshold and 1ms timeout. | Requires external 4.7kΩ pull-up; unsuitable for bidirectional reset I/Os like 68HC11; better for systems with single-master reset control. | Select MAX6315US30D1+T only if µP uses open-drain reset input and board layout already includes pull-up. |
| TPS3808G30DBVR | Push-pull RESET output; ±0.5% threshold accuracy; 2.93V nominal threshold (not 3.00V); 20ms default timeout (adjustable). | Higher accuracy and lower ICC (0.8µA), but lacks bidirectional support and active pull-up; requires external capacitor for timeout adjustment. | Choose TPS3808G30DBVR for ultra-low-power, high-accuracy applications where bidirectional reset detection is unnecessary. |
Compared with MAX6315US30D1+T and TPS3808G30DBVR, the MAX6314US30D1+T uniquely delivers integrated bidirectional reset signaling with active pull-up - essential for 68HC11-class µPs needing reset-source discrimination - while maintaining industry-standard 3.00V threshold and 1ms timeout in a compact SOT143 package.

FAQ
What is the exact reset threshold voltage for MAX6314US30D1+T?
The MAX6314US30D1+T has a factory-trimmed nominal reset threshold of 3.00V, with ±1.8% accuracy at +25°C and ±2.5% over the full –40°C to +85°C temperature range. This value is laser-trimmed during production and confirmed in the Electrical Characteristics table of the official datasheet.
Does MAX6314US30D1+T support bidirectional reset I/Os like the Motorola 68HC11?
Yes, the MAX6314US30D1+T is explicitly designed for bidirectional reset interfaces. Its RESET pin combines an N-channel pulldown, a 4.7kΩ passive pull-up, and a P-channel active pull-up, allowing µPs such as the 68HC11 to both drive and sense the line - enabling reset-source discrimination per the device's functional description.
What is the minimum reset timeout period for MAX6314US30D1+T?
The MAX6314US30D1+T has a minimum reset timeout period of 1ms, as indicated by the "D1" suffix in the part number. This is the shortest available timeout option in the MAX6314 family and is guaranteed across the full operating temperature range.
Can MAX6314US30D1+T operate from a 2.8V supply?
Yes, the MAX6314US30D1+T operates from 2.5V to 5.5V, so it functions correctly at 2.8V. However, note that the reset threshold remains fixed at 3.00V - meaning it will assert reset whenever VCC falls below 3.00V, which may occur immediately at startup if the supply cannot reach 3.00V.
Is an external pull-up resistor required for the RESET pin of MAX6314US30D1+T?
No, an external pull-up resistor is not required. The MAX6314US30D1+T integrates a 4.7kΩ pull-up resistor and a P-channel active pull-up transistor on the RESET pin, eliminating the need for external components while ensuring fast rise time even with capacitive loads up to 390pF.
