Product details
Overview
MAX6896AAZT+T from Maxim Integrated is an ultra-small, low-power, adjustable-voltage supervisory circuit with active-low enable and active-low push-pull output, designed for power-supply sequencing and reset control in automotive and industrial systems. It monitors input voltages down to 0.5V with ±1.8% threshold accuracy over temperature, supports 1.5V–5.5V supply, and provides capacitor-adjustable delay (40µs to >1s) from input rise or enable assertion to output assertion.
For engineers reviewing the MAX6896AAZT+T datasheet, MAX6896AAZT+T pinout, MAX6896AAZT+T application, or MAX6896AAZT+T equivalent, key selection considerations include its AEC-Q100-qualified operation at −40°C to +125°C, 10µA typical supply current, 6-pin thin SOT23 package (1.60mm × 2.90mm), and precise 0.5V monitor threshold with 5mV hysteresis.
Technical Context
The MAX6896AAZT+T implements a fixed 0.5V internal reference comparator driving an active-low push-pull output stage, with high-impedance IN input (±15nA leakage) enabling use of high-value external resistive dividers. Its ENABLE pin is active-low, requiring logic-high to deassert output immediately - independent of monitored voltage - and logic-low to assert output after capacitor-programmed delay when IN exceeds 0.5V.
Delay timing is governed by a 250nA internal current source charging an external capacitor (CDELAY) from GND; tDELAY = (CCDELAY × 4.0 × 10⁶) + 40µs. The device features undervoltage lockout (UVLO) at 1.20–1.35V and guarantees correct startup only after VCC exceeds 1.5V for ≥2ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V - supports wide-input rail monitoring without external regulators |
| Monitor Threshold | 0.5V ±1.8% over −40°C to +125°C - enables accurate low-voltage sequencing (e.g., 1.2V, 1.8V rails) |
| Hysteresis | 5mV - prevents output chatter during slow-rising/falling input transitions |
| Supply Current | 10µA typical at 3.3V - minimizes quiescent power in always-on monitoring circuits |
| Delay Range | 40µs to >1s via external capacitor (0–5000nF) - allows fine-grained timing control across power-up sequences |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial embedded environments |
| Output Type | Active-low push-pull - drives low directly without external pullup; sinks up to 90µA at 0.3V VOL |
Pinout & Package
MAX6896AAZT+T is housed in a 6-pin thin SOT23 package (1.60mm × 2.90mm, 0.95mm height), optimized for space-constrained PCB layouts and compatible with standard SOT23 pick-and-place equipment.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | ENABLE | Active-low logic-enable input; drive high to force immediate output deassertion (OUT = high), low to enable delayed assertion |
| 2 | GND | Ground reference for all internal circuitry and external capacitor (CDELAY) |
| 3 | IN | High-impedance monitor input (±15nA leakage); connects to resistive divider to set threshold voltage down to 0.5V |
| 4 | OUT | Active-low push-pull output; asserts low (≤0.3V at 90µA) when enabled and IN > 0.5V after delay; no external pullup required |
| 5 | CDELAY | Capacitor-adjustable delay node; internal 250nA current source charges external CCDELAY to 1.0V to trigger output assertion |
| 6 | VCC | Power supply input (1.5V–5.5V); requires local 0.1µF ceramic bypass to GND for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Qualified per AEC-Q100 Rev H for automotive applications - validated for reliability in harsh thermal and vibration environments |
| Adjustable Delay Timing | Programmable delay from 40µs to >1s using single external capacitor - eliminates need for multiple fixed-delay ICs in complex sequencing trees |
| Low-Power Operation | 10µA typical ICC enables battery-backed or energy-harvesting system monitoring without significant drain |
| Precision Threshold | 0.5V ±1.8% over full temperature range - ensures consistent reset/enable behavior across operating conditions |
| Wide Supply Range | 1.5V–5.5V operation - supports direct interface with Li-ion, 3.3V, and 5V rails without level-shifting |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervision and sequencing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6896PAAZT+T | Fixed 150ns enable-to-output propagation delay vs. capacitor-adjustable delay in MAX6896AAZT+T | Suitable where deterministic minimal latency is required instead of programmable sequencing intervals | Select MAX6896PAAZT+T for fast enable/disable response; MAX6896AAZT+T for flexible delay tuning |
| TLV809KDBZR | Single fixed 3.08V threshold, no adjustable delay, no enable input, SOT23-3 package | Limited to basic reset generation without sequencing capability or voltage adjustability | Choose TLV809KDBZR only for simple, low-cost reset-only functions; MAX6896AAZT+T adds sequencing, adjustability, and automotive qualification |

FAQ
What is the exact monitor threshold voltage of the MAX6896AAZT+T and how stable is it over temperature?
The MAX6896AAZT+T features a fixed 0.5V internal reference with ±1.8% accuracy over the full −40°C to +125°C operating range. This translates to a guaranteed threshold window of 0.491V to 0.509V across temperature, enabling reliable low-voltage rail monitoring for 1.2V, 1.8V, and 2.5V supplies when used with appropriate external resistive dividers.
Does the MAX6896AAZT+T require an external pullup resistor on its OUT pin?
No, the MAX6896AAZT+T uses an active-low push-pull output stage, so it actively drives the output low (≤0.3V at 90µA sink) and high (to VCC) without needing an external pullup resistor. This simplifies layout and eliminates pullup-related power loss or timing uncertainty - unlike open-drain alternatives such as the MAX6898AAZT+T.
How do I calculate the external capacitor value for a desired delay time with the MAX6896AAZT+T?
Use the formula tDELAY = (CCDELAY × 4.0 × 10⁶) + 40µs, where tDELAY is the total delay from IN rising above 0.5V (or ENABLE going low) to OUT asserting low, and CCDELAY is the capacitor value in farads. For example, a 100nF capacitor yields tDELAY ≈ 401ms. Ensure CCDELAY is a stable, low-leakage type (e.g., X7R ceramic) placed close to the CDELAY pin.
Is the MAX6896AAZT+T qualified for automotive applications?
Yes, the MAX6896AAZT+T is AEC-Q100 qualified (Grade 1, −40°C to +125°C), as confirmed in the official Maxim Integrated datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and electrical reliability - making it suitable for under-hood and infotainment applications in passenger vehicles and commercial vehicles.
What is the maximum voltage rating for the IN and ENABLE pins of the MAX6896AAZT+T?
The absolute maximum rating for both IN and ENABLE pins is −0.3V to +6V, independent of VCC. This allows safe interfacing with higher-voltage divider networks or logic families (e.g., 5V CMOS) without level shifters, provided the input current remains within ±15nA and the voltage stays within this range.
