Product details
Overview
MAX6384XS22D1+ from Maxim Integrated is a low-power microprocessor supervisory circuit with active-low push-pull reset output, factory-set 2.19V reset threshold (±2.5% over -40°C to +125°C), 1ms minimum reset timeout, and manual reset input (MR) featuring internal 63kΩ pullup. It monitors single supply voltage in portable/battery-powered systems and embedded controllers where reliable power-on reset and brownout protection are critical.
For engineers reviewing the MAX6384XS22D1+ datasheet, MAX6384XS22D1+ pinout, MAX6384XS22D1+ application, or MAX6384XS22D1+ equivalent, key selection criteria include guaranteed reset assertion down to VCC = 1V, 3μA supply current at +1.8V, 4-pin SC70 package compatibility, and MR debounce capability without external components.
Technical Context
The MAX6384XS22D1+ implements a precision bandgap-based reset comparator with ±2.5% threshold accuracy across -40°C to +125°C and 60ppm/°C tempco. Its internal timer generates a fixed 1ms minimum reset timeout after VCC rises above 2.19V or after MR release.
It features a debounced manual reset input (MR) with 1µs minimum pulse width support and 100ns glitch rejection, and guarantees valid reset output state for VCC ≥ 1V - enabling robust operation during deep brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.19V nominal (SUFFIX 22), ±2.5% over -40°C to +125°C - ensures consistent reset activation across automotive and industrial temperature ranges |
| Reset Timeout | 1ms minimum (SUFFIX D1) - provides sufficient hold time for microprocessor initialization before code execution |
| Supply Current | 3μA at +1.8V - enables multi-year battery life in always-on monitoring applications |
| Reset Output Type | Active-low push-pull - eliminates need for external pullup resistor and supports direct connection to μP RESET pin |
| Manual Reset Input | MR with 63kΩ internal pullup - allows momentary switch interface without external components; valid down to VCC = 1V |
| Operating Voltage | 1.0V to 5.5V - supports operation during severe brownout and compatibility with 1.2V–5V logic domains |
| Package | 4-pin SC70 (XS prefix) - 1.3mm × 1.1mm footprint ideal for space-constrained portable designs |
Pinout & Package
The MAX6384XS22D1+ is housed in a RoHS-compliant 4-pin SC70 package (1.3mm × 1.1mm, 0.5mm pitch), optimized for high-density PCB layouts in portable electronics.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Primary supply input and monitored voltage rail; powers internal circuitry and serves as reference for reset threshold detection |
| 2 | RESET | Active-low push-pull output; drives low during reset assertion and high-impedance when deasserted - directly interfaces with μP RESET pin |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC via 63kΩ resistor - enables hardware-initiated reset using momentary switch to GND |
| 4 | GND | Analog and digital ground reference; must be connected to system ground plane for accurate threshold sensing and noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 2.19V with ±2.5% tolerance over full temperature range - eliminates need for external resistor divider calibration |
| Ultra-low quiescent current | 3μA at +1.8V - extends battery life in coin-cell–powered IoT sensors and wearables |
| Guaranteed reset validity | RESET output remains logically valid down to VCC = 1V - prevents spurious resets during deep undervoltage events |
| Integrated MR pullup | 63kΩ internal resistor - reduces BOM count and PCB area versus discrete pullup solutions |
| Negative-going transient immunity | Immune to VCC glitches ≤35µs at 100mV overdrive - suppresses false resets from switching noise or ESD-induced supply dips |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD1+T | 2.93V reset threshold, no MR input, 3-pin SC70 package | Lacks manual reset capability; suited only for basic VCC-only monitoring | Select when MR functionality is unnecessary and higher threshold aligns with 3.3V system requirements |
| TPS3808G12DBVR | 1.2V threshold option, adjustable timeout via capacitor, SOT-23-5 package | Requires external timing capacitor; higher 8μA ICC at 1.8V vs. 3μA for MAX6384XS22D1+ | Choose when programmable timeout or lower threshold is required, accepting larger footprint and higher current |
Compared with MAX809TRD1+T and TPS3808G12DBVR, the MAX6384XS22D1+ uniquely combines 2.19V threshold, 1ms fixed timeout, MR input with integrated pullup, and 4-pin SC70 packaging - delivering optimal balance of precision, integration, and space efficiency for 1.8V–2.5V battery-powered systems.

FAQ
What is the exact reset threshold voltage of the MAX6384XS22D1+?
The MAX6384XS22D1+ has a factory-set nominal reset threshold of 2.19V, with guaranteed tolerance of ±2.5% over the full operating temperature range (-40°C to +125°C). This value is defined by the "22" suffix per the Reset Threshold table in the datasheet and applies specifically to the MAX6384XS22D1+ variant.
Does the MAX6384XS22D1+ require an external pullup resistor on the RESET pin?
No, the MAX6384XS22D1+ features an active-low push-pull RESET output, so no external pullup resistor is needed. The output actively drives low during reset assertion and high during deassertion, enabling direct connection to standard microprocessor RESET inputs without additional components.
What is the function and electrical behavior of the MR pin on the MAX6384XS22D1+?
The MR pin on the MAX6384XS22D1+ is an active-low manual reset input with an internal 63kΩ pullup resistor to VCC. Driving MR low forces reset assertion; reset remains active for the full 1ms timeout after MR is released. The pin accepts TTL/CMOS logic levels and requires no external debounce circuitry due to built-in filtering.
Can the MAX6384XS22D1+ operate reliably at VCC = 1.2V?
Yes, the MAX6384XS22D1+ guarantees correct reset output logic state down to VCC = 1.0V, including at 1.2V. Its internal circuitry remains functional and the RESET output remains valid, making it suitable for ultra-low-voltage applications such as energy-harvesting systems or deeply scaled logic domains where supply rails dip near 1V.
What package type and dimensions does the MAX6384XS22D1+ use?
The MAX6384XS22D1+ uses a 4-pin SC70 package (package code XS), measuring 1.3mm × 1.1mm with 0.5mm lead pitch. This RoHS-compliant, surface-mount package is optimized for high-density PCB layouts in portable and wearable electronics, and is distinct from the 3-pin SC70 used by earlier MAX6381 variants.
