Product details
Overview
MAX16004BTP+T from Maxim Integrated is a low-voltage, hex-voltage microprocessor supervisor IC in a 19-pin TQFN (4mm × 4mm) package, monitoring six independent supply rails (IN1–IN6) with fixed and adjustable thresholds (e.g., 3.3V, 1.8V, down to 0.4V), featuring an active-low RESET output, watchdog timer (1.6s typ), manual reset (MR), margin enable, and tolerance-select inputs. It is used in multivoltage server power sequencing and ASIC supervisory systems.
For engineers reviewing the MAX16004BTP+T datasheet, MAX16004BTP+T pinout, MAX16004BTP+T application, or MAX16004BTP+T equivalent, key selection considerations include its 6-channel monitoring capability, 140ms minimum reset timeout (capacitor-adjustable), -40°C to +125°C operation, internal 30µA pullups on all open-drain outputs, and watchdog startup delay of 54s after reset assertion.
Technical Context
The MAX16004BTP+T implements a deterministic reset architecture where RESET asserts whenever any monitored voltage falls below its threshold or MR is pulled low, remaining asserted for the full timeout period after all voltages recover and MR is released. Its watchdog timer clears on any WDI edge and enters a 54s startup window before first timeout enforcement.
Threshold selection is controlled by the TOL pin (5% or 10% tolerance), while MARGIN provides active-low deassertion of all outputs during system margin testing. All six IN_ inputs support hysteresis (0.5% VTH) and operate correctly down to VCC = 1V, ensuring robust supervision under brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Channels | 6 independent voltage inputs (IN1–IN6), configurable via part variant B (3.3V/ADJ/ADJ/1.8V/ADJ/ADJ) |
| Reset Timeout | 140ms minimum (internally set); adjustable up to ~3.92ms using external capacitor on SRT pin |
| Watchdog Timeout | 1.6s typical; 54s startup delay after reset assertion before first timeout |
| Supply Voltage Range | 1.0V to 5.5V; guaranteed correct logic state down to VCC = 1V |
| Operating Temperature | -40°C to +125°C - qualified for industrial and extended-temperature embedded systems |
| Output Type | All outputs open-drain with internal 30µA pullup to VCC; no external resistors required |
| Threshold Accuracy | ±1.25% for fixed thresholds (e.g., 3.3V @ TOL=GND); ±2.5% for adjustable mode (0.4V min) |
Pinout & Package
MAX16004BTP+T is housed in a 19-pin, 4mm × 4mm TQFN package with exposed pad (EP) connected internally to GND. Pinout follows the MAX16004-specific configuration shown in the datasheet Figure 7 (top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 13–15, 19 | IN1–IN6 | 6 monitored voltage inputs; each triggers dedicated output or global RESET when falling below threshold |
| 3, 4, 6, 7, 10–12, 16–18 | OUT1–OUT6 | Independent open-drain outputs per channel; high-impedance when voltage OK, pulled low on fault |
| 5 | GND | Power ground reference; EP must be soldered to PCB ground plane for thermal management |
| 8 | VCC | Unmonitored supply input (1.0–5.5V); requires 0.1µF bypass capacitor to GND |
| 9 | MARGIN | Active-low input to force all outputs high during margin testing - overrides all voltage faults |
| 17 | TOL | Selects threshold tolerance: GND = ±5%, VCC = ±10% - sets hysteresis and accuracy band |
| 18 | MR | Active-low manual reset; asserts RESET and initiates timeout upon release (200ns glitch rejection) |
| 19 | SRT | Set Reset Timeout; connect to VCC for 140ms min, or to GND via capacitor for longer delays (tRP ≈ 2.06MΩ × CSRT) |
| - | WDI | Watchdog input; edge-sensitive; left open disables watchdog (100nA leakage, ≤50nA load) |
| - | RESET | Active-low global reset output; asserts if any IN_ fails or MR is asserted; 30µA internal pullup |
Key Features
| Feature | Design Value |
|---|---|
| 6-channel independent monitoring | Enables discrete fault isolation across complex multivoltage ASIC or FPGA power domains |
| Capacitor-adjustable reset timeout | Supports system-specific power-up sequencing windows without firmware dependency |
| Integrated 30µA internal pullups | Eliminates 6 external pullup resistors - reduces BOM count and board area in dense layouts |
| 54s watchdog startup delay | Allows safe boot time for slow-starting processors before watchdog enforcement begins |
| Margin enable function | Permits live voltage margining without disabling supervision - critical for production test validation |
| Guaranteed operation down to VCC = 1V | Ensures reliable reset assertion during deep brownout or battery-depleted conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16003BTP+T | Same 6-channel architecture and pinout, but lacks watchdog timer functionality | Suitable only where system-level software or external logic handles hang detection | Select when watchdog is unnecessary and lower cost or reduced feature set is acceptable |
| TPS3808G33DBVR | Single-supply supervisor (3.3V fixed), no multi-rail monitoring, no watchdog startup delay | Designed for simple single-rail systems; cannot replace 6-channel supervision directly | Use only as partial substitute in non-critical auxiliary rails where full MAX16004BTP+T functionality is over-specified |
Compared with MAX16003BTP+T and TPS3808G33DBVR, MAX16004BTP+T uniquely combines six independent voltage monitors, capacitor-adjustable reset timeout, and a 54s watchdog startup window - making it irreplaceable in complex multivoltage systems requiring both comprehensive fault coverage and safe boot sequencing.

FAQ
What is the exact pin count and package type of MAX16004BTP+T?
MAX16004BTP+T uses a 19-pin, 4mm × 4mm TQFN package with exposed pad (EP). The pinout is defined in the MAX16004-specific configuration (Figure 7 of the datasheet), including six IN_, six OUT_, VCC, GND, MR, MARGIN, TOL, SRT, and WDI - totaling 19 terminals. The EP is electrically tied to GND and must be soldered to the PCB ground plane.
How does the watchdog timer in MAX16004BTP+T behave during system startup?
The MAX16004BTP+T watchdog timer enforces a 54-second startup delay after RESET assertion before beginning timeout monitoring. This allows ample time for processor initialization and firmware execution before watchdog enforcement begins. The timer resets on any rising or falling edge at WDI and remains disabled if WDI is left floating.
Can MAX16004BTP+T monitor voltages below 1.0V?
Yes - MAX16004BTP+T supports adjustable thresholds down to 0.4V (typical) when configured in adjustable mode (TOL = VCC). Fixed thresholds start at 0.9V, but the adjustable input stage enables precise monitoring of sub-1V core rails such as modern ARM or RISC-V processor cores.
What is the role of the MARGIN pin on MAX16004BTP+T?
The MARGIN pin on MAX16004BTP+T is an active-low input that forces all OUT_ outputs and RESET into a high-impedance (deasserted) state regardless of monitored voltage conditions. This enables live voltage margin testing - intentionally stressing rails while maintaining system visibility - without disabling supervision logic.
Does MAX16004BTP+T require external pullup resistors on its outputs?
No - MAX16004BTP+T integrates 30µA internal pullups on all open-drain outputs (OUT1–OUT6 and RESET), eliminating the need for external pullup resistors. Each output can also be driven by an external voltage up to 5.5V, supporting mixed-voltage system interfacing without level shifters.
