Product details
Overview
MAX6465UR17+T from Maxim Integrated is a micropower supervisory circuit with active-high push-pull output, 1.700V lower trip threshold (VTH−), ±2.5% threshold accuracy over −40°C to +125°C, 150ms minimum reset timeout, and 1.0µA supply current at 3.6V - used for reliable power-on reset generation in battery-powered microcontroller systems.
For engineers reviewing the MAX6465UR17+T datasheet, MAX6465UR17+T pinout, MAX6465UR17+T application, or MAX6465UR17+T equivalent, this page delivers verified functional identity, package mapping, timing behavior, output stage configuration, and real-world selection guidance - all grounded in Maxim's official documentation for the SOT23-3 variant.
Technical Context
The MAX6465UR17+T implements a precision bandgap reference and comparator with internally trimmed resistor networks to set VTH− = 1.700V (typ) and VTH+ = VTH− × 1.05 = 1.785V (typ), enabling hysteresis-based voltage monitoring without external components. Its internal 150ms reset timeout ensures stable µP initialization after power-up or brownout recovery.
It operates across 1.2V to 6.0V supply range, consumes only 1.0µA (typ) at 3.6V, and guarantees ±2.5% threshold accuracy over full −40°C to +125°C industrial temperature range - making it suitable for harsh-environment embedded control where low quiescent current and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold (VTH−) | 1.700V (typ), 1.658V–1.743V (min/max over −40°C to +125°C) - sets precise undervoltage detection point for 1.8V rail supervision. |
| Supply Current | 1.0µA (typ) at 3.6V - enables multi-year operation on coin-cell batteries in always-on monitoring applications. |
| Reset Timeout Period | 150ms (min), 260ms (typ), 430ms (max) - ensures µP remains held in reset long enough for power rails and clocks to stabilize. |
| Threshold Accuracy | ±2.5% over −40°C to +125°C - eliminates need for system-level calibration in wide-temperature deployments. |
| Output Type | Active-high push-pull - drives high without external pullup; sinks ≤9mA at VCC ≥ 4.5V with VOL ≤ 0.4V. |
| Hysteresis | 5% (VTH+ / VTH− = 1.05) - prevents output chatter during slow-rising/falling supply transitions near threshold. |
| Propagation Delay | Not applicable - MAX6465 is a supervisory circuit (not detector); timeout dominates response timing. |
Pinout & Package
MAX6465UR17+T is housed in a lead-free 3-pin SOT23-3 package (JEDEC MO-178AA), with 1.3mm × 2.9mm footprint and 0.95mm height - compatible with standard reflow profiles and space-constrained PCB layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Active-high push-pull reset output; asserts high when VCC < VTH− and holds high for ≥150ms after VCC > VTH+. |
| 2 | GND | Ground reference for internal bandgap and comparator; must be connected directly to system ground plane. |
| 3 | VCC | Supply input and monitored voltage rail; operates from 1.2V to 6.0V; powers internal circuitry and defines detection target. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 1.0µA typical at 3.6V - extends battery life in portable medical devices and IoT sensors. |
| Factory-trimmed threshold | VTH− = 1.700V (±2.5% over temp) - removes need for external resistive divider or calibration in production. |
| Guaranteed reset timeout | 150ms minimum - meets µP reset timing requirements without external RC network or watchdog IC. |
| No external components required | Self-contained bandgap, comparator, hysteresis, and timer - reduces BOM count and layout area by ≥3 parts. |
| High-noise immunity | Immune to short VCC transients (<10µs at 100mV overdrive) - prevents false resets in electrically noisy environments. |
Applications
| Portable Medical Sensors | Industrial PLC I/O Modules |
|---|---|
|
Use Scenario: Continuous glucose monitor powered by CR2032 coin cell, requiring guaranteed reset during cold-start and battery depletion. IC Role / Device Role / Timing Role: Supervisory circuit asserting active-high reset to ARM Cortex-M0+ MCU until 1.7V rail stabilizes post-power-up. Use Value: 1.0µA quiescent current enables >5-year shelf life; ±2.5% threshold accuracy ensures consistent reset behavior across operating temperature range. |
Use Scenario: DIN-rail mounted I/O module exposed to −40°C ambient, with 3.3V logic rail derived from isolated DC/DC converter. IC Role / Device Role / Timing Role: Voltage supervisor holding µP in reset during input undervoltage events caused by line sags or converter faults. Use Value: 150ms timeout prevents spurious firmware execution; operation to +125°C junction temperature supports convection-cooled enclosures. |
| Smart Utility Meters | Wearables with Low-Voltage RF SoCs |
|
Use Scenario: AMI meter using sub-GHz RF transceiver, where brownout on 1.8V analog supply must trigger controlled shutdown before data corruption. IC Role / Device Role / Timing Role: Reset generator tied to 1.8V rail, asserting active-high signal to enable sequenced power-down of RF and MCU domains. Use Value: 5% hysteresis prevents oscillation during slow rail collapse; push-pull output eliminates need for pullup resistor in high-density meter PCB. |
Use Scenario: Fitness tracker with BLE SoC (nRF52832) and 1.7V LDO output, requiring deterministic reset if battery voltage drops below operational minimum. IC Role / Device Role / Timing Role: Dedicated supervisor monitoring LDO output, generating clean reset pulse to SoC's nRESET pin. Use Value: Matched 1.700V threshold aligns precisely with SoC's 1.7V VDD min spec; SOT23-3 package fits 2.0mm × 2.0mm wearable PCB constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar µP supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G17DBVR | 1.7V threshold, 200ms timeout, 1.1µA ICC, SOT23-6 package - requires external capacitor for timeout adjustment; no factory-fixed 150ms option. | Used where adjustable timeout or higher sink current (100mA) is needed; not drop-in due to extra pin and different pinout. | Select TPS3808G17DBVR only if timeout flexibility or higher drive strength outweighs added BOM and layout complexity. |
| ADM6315-17ARTZ-RL7 | 1.7V threshold, 240ms timeout, 2.5µA ICC, SOT23-3 - active-low open-drain output; no push-pull active-high variant available. | Suitable for legacy designs using active-low reset logic; requires external pullup and level-shifting for active-high µP interfaces. | Choose ADM6315-17ARTZ-RL7 only when active-low signaling is already standardized in the target platform. |
Compared with MAX6465UR17+T, TPS3808G17DBVR adds configurability at the cost of pin count and fixed-timing simplicity, while ADM6315-17ARTZ-RL7 trades ultra-low ICC for output polarity mismatch - making MAX6465UR17+T the optimal choice for space-constrained, active-high, fixed-timing µP reset needs.

FAQ
What is the exact reset threshold voltage of MAX6465UR17+T?
The MAX6465UR17+T has a nominal lower trip threshold (VTH−) of 1.700V at +25°C, with guaranteed range of 1.658V to 1.743V over −40°C to +125°C. The upper threshold (VTH+) is VTH− × 1.05, resulting in 1.785V (typ) - both values are factory-trimmed and require no external calibration. This matches the "17" suffix per Maxim's Table 1a.
Does MAX6465UR17+T require an external pullup resistor on its output?
No, MAX6465UR17+T features an active-high push-pull output stage, so it actively drives high without needing an external pullup resistor. This simplifies layout and reduces component count compared to open-drain alternatives. The output can source up to 8mA at VCC ≥ 4.5V while maintaining VOH ≥ 0.8 × VCC.
What is the minimum reset timeout period of MAX6465UR17+T?
The MAX6465UR17+T guarantees a minimum reset timeout period of 150ms after VCC rises above VTH+, with typical value of 260ms and maximum of 430ms over temperature. This built-in delay replaces external RC networks and ensures µP reset assertion meets JEDEC and ARM specification requirements for reliable boot sequencing.
Can MAX6465UR17+T operate from a 1.2V supply?
Yes, MAX6465UR17+T is fully specified to operate from VCC = 1.2V to 6.0V. However, its 1.700V threshold means it will assert reset whenever VCC falls below that level - so it is intended for monitoring rails ≥1.7V (e.g., 1.8V, 2.5V, 3.3V). At 1.2V supply, the device remains functional but cannot supervise voltages below its own threshold.
Is MAX6465UR17+T pin-compatible with other parts in the MAX6461–MAX6466 family?
Yes, MAX6465UR17+T shares identical SOT23-3 pinout (VCC, GND, OUT) with all UR-suffix variants (e.g., MAX6461URxx+T, MAX6462URxx+T), differing only in function (voltage detector vs. supervisory) and threshold. However, it is not pin-compatible with XR (SC70-3) or UK (SOT23-5) variants due to different pin counts and arrangements.
