Product details
Overview
MAX6375XR29+ from Maxim Integrated is an ultra-low-power, active-low voltage detector in SC70-3 package with factory-trimmed 2.93V threshold, ±2.5% accuracy over temperature, 500nA supply current, and push-pull output-designed for precision battery monitoring in portable medical sensors and low-power IoT edge nodes.
For engineers reviewing the MAX6375XR29+ datasheet, MAX6375XR29+ pinout, MAX6375XR29+ application, or MAX6375XR29+ equivalent, key selection criteria include reset threshold tolerance, VCC operating range down to 1V, transient immunity, SC70 footprint constraints, and compatibility with 1.8V/3.3V logic interfaces.
Technical Context
The MAX6375XR29+ integrates a precision bandgap reference, comparator, and laser-trimmed resistive divider to deliver fixed 2.93V detection without external components. It asserts a logic-low output when VCC falls below threshold and holds valid state down to 1V supply.
Its push-pull output drives directly into CMOS inputs with VOL ≤ 0.4V at 100µA sink, while propagation delay is 6.3µs (typ) with hysteresis of 100mV-optimized to reject fast transients up to 200µs duration at 100mV overdrive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93V (±2.5% over -40°C to +85°C)-ensures reliable brown-out detection for 3.0V Li-ion systems. |
| Supply Current | 0.5µA (max) at +25°C-enables multi-year battery life in always-on sensor nodes. |
| Output Type | Active-low push-pull-eliminates need for external pull-up resistor in 3.3V microcontroller reset circuits. |
| VCC Operating Range | 1.2V to 5.5V-supports operation during deep discharge and across multiple rail domains. |
| Propagation Delay | 6.3µs (typ) at +25°C-provides fast response while maintaining noise immunity. |
| Hysteresis | 100mV-prevents chatter during slow-ramping or noisy supply recovery. |
| Tempco | 40ppm/°C-minimizes threshold drift across industrial temperature range. |
Pinout & Package
MAX6375XR29+ is housed in a 3-pin SC70-3 package (1.25mm × 1.65mm × 0.95mm), compatible with high-density PCB layouts and reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Reference ground return-must be connected directly to low-impedance system ground plane. |
| 2 | OUT | Active-low push-pull output-drives MCU reset pin directly; sinks 100µA with VOL ≤ 0.4V. |
| 3 | VCC | Supply input-accepts 1.2V–5.5V; internal circuitry remains functional down to 1V for latched state retention. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 0.5µA max enables >10-year coin-cell operation in wireless sensor transmitters. |
| No external components | Factory-trimmed threshold eliminates calibration resistors and reduces BOM count by one part. |
| Transient immunity | Rejects VCC glitches ≤200µs at 100mV overdrive-avoids false resets in noisy power environments. |
| 1V minimum VCC support | Maintains correct output logic state during deep brown-out, ensuring deterministic reset behavior. |
| SC70-3 footprint | 1.25mm × 1.65mm area saves >40% board space vs. SOT23-3 in wearables and hearing aids. |
Applications
| Wearable Health Monitor | Industrial Sensor Node |
|---|---|
|
Use Scenario: Continuous ECG patch powered by CR2032 coin cell with 2.8–3.1V operating range. IC Role / Device Role / Timing Role: Voltage supervisor asserting MCU reset if battery drops below 2.93V to prevent data corruption during low-voltage write cycles. Use Value: 0.5µA quiescent current extends usable battery life to 3.2 years; SC70-3 fits within 8mm² wearable PCB constraint. |
Use Scenario: LoRaWAN node with 3.3V LDO supplying MCU and RF transceiver in remote pipeline monitoring. IC Role / Device Role / Timing Role: Brown-out detector triggering controlled shutdown before supply collapse corrupts flash memory or sensor registers. Use Value: 6.3µs propagation delay ensures timely reset assertion; ±2.5% threshold accuracy prevents premature shutdown at cold temperatures. |
| Smart Meter Battery Backup | Portable Diagnostic Tool |
|
Use Scenario: Lithium-thionyl chloride backup battery (3.6V nominal) powering real-time clock and nonvolatile memory during AC failure. IC Role / Device Role / Timing Role: Supervisory IC enabling safe RTC save-and-halt sequence when main supply fails and backup voltage crosses 2.93V threshold. Use Value: Push-pull output drives RTC reset pin directly-no pull-up required-reducing leakage path and simplifying layout. |
Use Scenario: Handheld ultrasound probe with dual 3.0V/5.0V rails and ARM Cortex-M4 processor requiring clean reset under varying battery load. IC Role / Device Role / Timing Role: Primary voltage monitor on 3.0V analog front-end rail, asserting reset if supply sags during high-current transducer pulse. Use Value: 100mV hysteresis prevents oscillation during marginal supply recovery; 1.2V–5.5V VCC range supports both rail domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EC29DBZR | 2.93V threshold, 350nA ICC, SOT23-3 only, no SC70 option | Limited to SOT23-3; lacks SC70 footprint for ultra-compact designs | Select when SOT23-3 is preferred and lowest possible ICC is critical |
| TPS3801K29DBVR | 2.93V threshold, 1.1µA ICC, open-drain output, SC70-3 available | Requires external pull-up; higher ICC reduces battery life in always-on use | Select when open-drain flexibility (e.g., wired-OR reset bus) outweighs current penalty |
Compared with TLV803EC29DBZR and TPS3801K29DBVR, the MAX6375XR29+ uniquely combines SC70-3 packaging, 0.5µA max ICC, and push-pull output-making it optimal for space-constrained, ultra-low-power battery systems where reset signal integrity and minimal BOM are essential.

FAQ
What is the exact reset threshold voltage of the MAX6375XR29+?
The MAX6375XR29+ has a factory-trimmed nominal reset threshold of 2.93V, with guaranteed tolerance of ±2.5% over the full -40°C to +85°C temperature range. At +25°C, the typical threshold is 2.93V, and the min/max limits are 2.857V and 3.000V respectively-verified per Table 1 in the official datasheet.
Does the MAX6375XR29+ require any external components to operate?
No, the MAX6375XR29+ requires zero external components. Its precision bandgap reference, comparator, and laser-trimmed resistor network are fully integrated. The device operates with only VCC, GND, and OUT connections-eliminating calibration resistors, capacitors, or pull-ups needed by discrete solutions.
What is the maximum VCC voltage the MAX6375XR29+ can tolerate?
The MAX6375XR29+ supports a VCC operating range of 1.2V to 5.5V, with absolute maximum rating of +6V. It maintains correct output logic state down to 1V VCC, but guaranteed functional operation begins at 1.2V. Exceeding 6V on VCC risks permanent damage per Absolute Maximum Ratings.
Is the MAX6375XR29+ pin-compatible with other parts in the MAX6375–MAX6380 family?
Yes, all MAX6375–MAX6380 variants-including MAX6375XR29+-share identical SC70-3 and SOT23-3 pinouts. Pin 1 is GND, Pin 2 is OUT, and Pin 3 is VCC across the entire family, enabling direct substitution when threshold and output logic match design requirements.
What does the "+" suffix in MAX6375XR29+ indicate?
Per Maxim's ordering convention, the "+" suffix in MAX6375XR29+ denotes lead-free, RoHS-compliant packaging. It replaces the standard "-T" suffix (e.g., MAX6375XR29-T) and confirms compliance with JEDEC J-STD-020 moisture sensitivity level 1 and Pb-free solder reflow profiles.
