Product details
Overview
MAX6410BS46 from Maxim Integrated is an ultra-low-power, active-high push-pull voltage detector IC designed for battery and power-supply monitoring in portable electronics. It features a factory-trimmed 4.63V threshold (±2.5% over –40°C to +85°C), 500nA supply current, manual reset input (MR), and guaranteed valid output down to VCC = 1.0V. It is used in Li+-based MP3 players to trigger controlled shutdown before brownout.
For engineers reviewing the MAX6410BS46 datasheet, MAX6410BS46 pinout, MAX6410BS46 application, or MAX6410BS46 equivalent, key selection criteria include its 4.63V detection threshold, active-high push-pull output logic, UCSP-4 package compatibility, and immunity to sub-100ns VCC transients - critical for reliable power sequencing in space-constrained battery-powered systems.
Technical Context
The MAX6410BS46 implements a precision bandgap reference comparator with hysteresis of 9.5mV and temperature coefficient of 40ppm/°C, ensuring stable trip-point performance across industrial temperature range (–40°C to +85°C). Its internal 50kΩ MR pullup enables direct interface with momentary switches or CMOS logic without external components.
It operates across VCC = 1.2V to 5.5V and asserts OUT high when VCC falls below 4.63V. Propagation delay is 42µs (VCC falling) and 100µs (VCC rising), with startup time of 88µs from VCC = 0 to threshold - optimized for fast, deterministic reset generation in low-voltage microcontroller systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Detection Threshold | 4.63V ±2.5% (–40°C to +85°C); ensures accurate brownout detection for 4.8V nominal Li+ battery systems. |
| Supply Current | 500nA at VCC = 3V; enables multi-year battery life in always-on monitoring applications like pagers and wearables. |
| Output Type | Active-high push-pull; drives logic-high reset directly into µP RESET pin without external pullup or level-shifting. |
| Manual Reset Input | MR with 50kΩ internal pullup; supports TTL/CMOS-compatible reset initiation via switch or digital signal. |
| VCC Operating Range | 1.2V to 5.5V; guarantees functional output state down to 1.0V - supports operation during deep discharge or cold-start conditions. |
| Propagation Delay | 42µs (VCC falling), 100µs (VCC rising); provides predictable timing margin for synchronous system reset coordination. |
| Hysteresis | 9.5mV; prevents output chatter near threshold during slow-ramping or noisy supply conditions. |
Pinout & Package
MAX6410BS46 is housed in a 4-bump (2 × 2 mm) UCSP (Ultra-Compact Silicon Package), compatible with fine-pitch SMT assembly and offering 70% smaller footprint than SC70.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (A1) | Ground reference | Primary return path for internal comparator and output stage; must be low-impedance connection to system ground plane. |
| VCC (A2) | Supply and sense input | Monitored voltage source; powers device and serves as input to precision bandgap comparator. |
| OUT (B1) | Active-high push-pull output | Drives high (≥0.8×VCC) when VCC < 4.63V; sinks current when deasserted - directly interfaces µP reset inputs. |
| MR (B2) | Active-low manual reset | Pulls OUT high when asserted low; internal 50kΩ pullup allows NC or VCC tie-off if unused. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 4.63V threshold | Eliminates external resistor dividers and calibration, reducing BOM count and layout area in compact handheld designs. |
| 500nA quiescent current | Enables continuous monitoring in coin-cell-powered devices with >10-year shelf-life requirements. |
| Guaranteed output validity to VCC = 1.0V | Ensures deterministic reset assertion even during severe battery sag or cold-temperature discharge. |
| Immunity to VCC transients ≤100ns | Rejects ESD-induced or switching-noise glitches without false triggering - no external RC filtering required. |
| No external components required | Reduces design validation effort and improves long-term reliability by removing passive component failure modes. |
Applications
| Li+ Battery Protection Circuit | MP3 Player Power Sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6409BS46 | Same 4.63V threshold and UCSP-4 package, but active-low push-pull output. | Requires inverted reset logic handling in µP or external inverter; unsuitable where active-high reset is mandated by SoC spec. | Select MAX6409BS46 only if target MCU accepts active-low reset and board layout cannot accommodate signal inversion. |
| TLV803EB46DBZR | 4.63V threshold, SOT-23-3 package, 1.8µA supply current, no manual reset input. | Lacks MR functionality; higher ICC reduces battery lifetime in always-on monitoring; larger footprint limits ultra-compact designs. | Choose TLV803EB46DBZR only when MR is unnecessary and SOT-23 assembly infrastructure is already established. |
Compared with MAX6409BS46 and TLV803EB46DBZR, MAX6410BS46 uniquely delivers active-high reset, ultra-low 500nA ICC, and integrated MR - making it optimal for space- and power-constrained portable systems requiring deterministic, low-overhead supervision.

FAQ
What is the exact factory-trimmed threshold voltage of MAX6410BS46?
The MAX6410BS46 has a nominal detection threshold of 4.63V, with tolerance of ±2.5% over the full operating temperature range (–40°C to +85°C). This value is laser-trimmed at wafer test and confirmed per Table 1 in the datasheet; the "46" suffix explicitly denotes the 4.63V variant within the MAX6410 series.
Does MAX6410BS46 require external components to operate?
No, MAX6410BS46 requires no external components. Its precision bandgap reference, comparator, and 50kΩ MR pullup resistor are fully integrated. Only VCC, GND, MR (optional), and OUT connections are needed - eliminating resistors, capacitors, or trimming circuits typically required in discrete supervisor designs.
Can MAX6410BS46 drive a standard microcontroller reset input directly?
Yes, MAX6410BS46 can drive most µP reset inputs directly. Its active-high push-pull output delivers VOH ≥ 0.8×VCC at 500µA source current and VOL ≤ 0.4V at 3.2mA sink current, meeting standard CMOS reset voltage thresholds across its 1.2V–5.5V VCC range without level-shifting circuitry.
What is the maximum transient duration that MAX6410BS46 can ignore on the VCC line?
MAX6410BS46 rejects negative-going VCC transients up to 100ns in duration when the overdrive (VTH – VCC) is ≥20mV, as shown in Figure 4 of the datasheet. This immunity eliminates need for external RC filters in noisy DC/DC converter environments common in portable audio devices.
Is MAX6410BS46 available in RoHS-compliant packaging?
Yes, MAX6410BS46 is available in RoHS-compliant, lead-free tape-and-reel packaging. The part number suffix "+T" (e.g., MAX6410BS46+T) indicates RoHS/lead-free compliance per Maxim's naming convention and is supported by materials analysis documentation on the manufacturer's website.
