Product details
Overview
MAX6896PAZT+ from Maxim Integrated is an ultra-small, low-power, active-low enable / active-low push-pull voltage supervisor with capacitor-adjustable sequencing delay and 0.5V fixed threshold monitoring. It operates from 1.5V to 5.5V supply, delivers 150ns enable-to-output propagation delay (P version), supports -40°C to +125°C operation, and is housed in a 6-pin thin SOT23 package. It is used for precise power-supply sequencing in automotive and industrial embedded systems.
For engineers reviewing the MAX6896PAZT+ datasheet, MAX6896PAZT+ pinout, MAX6896PAZT+ application, or MAX6896PAZT+ equivalent, key selection considerations include its active-low enable logic, active-low push-pull output, 150ns fixed enable propagation delay (not capacitor-adjustable), 0.5V monitor threshold with 5mV hysteresis, and compatibility with high-impedance resistive divider networks for sub-1V rail monitoring.
Technical Context
The MAX6896PAZT+ implements a fixed 150ns enable-to-output propagation delay (tPROPP) - distinct from the capacitor-adjustable delay of A-version parts - enabling deterministic, glitch-immune assertion/deassertion timing independent of external capacitance. Its internal 0.5V comparator monitors IN with ±15nA input leakage and 5mV hysteresis, while ENABLE accepts logic-low activation with VIH = 1.4V and VIL = 0.4V thresholds.
This device uses BiCMOS process technology and features push-pull output referenced to VCC, capable of sourcing up to 500µA at VOH ≥ 0.8×VCC and sinking up to 1mA at VOL ≤ 0.4V (VCC ≥ 4.5V). It includes undervoltage lockout (UVLO) at 1.20–1.35V and draws only 10µA typical supply current across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V - supports wide-input rail monitoring including 1.8V, 2.5V, 3.3V, and 5V systems without external regulation. |
| Monitor Threshold | 0.5V ±0.9% (1.8% over temp) - enables accurate monitoring of low-voltage rails (e.g., 1.2V via 2.4:1 resistor divider) with minimal error from input leakage. |
| Enable Propagation Delay | 150ns (typ) - provides deterministic, fast enable response for time-critical sequencing; no capacitor dependency unlike A versions. |
| Output Type | Active-low push-pull - drives OUT low when asserted (VIN > 0.5V & ENABLE low), eliminating need for external pullup; compatible with standard CMOS inputs. |
| Supply Current | 10µA (typ) at 3.3V - enables battery-backed or always-on monitoring in ultra-low-power applications such as automotive body control modules. |
| Operating Temperature | -40°C to +125°C - fully specified for under-hood automotive, industrial PLC, and medical equipment environments. |
| Input Hysteresis | 5mV - prevents chatter during slow-rising/falling rail transitions, ensuring clean reset or enable assertion without external filtering. |
Pinout & Package
MAX6896PAZT+ is supplied in a 6-pin thin SOT23 package (1.60mm × 2.90mm, 0.95mm height), JEDEC MO-178AA compliant, with θJA = 110°C/W. Pin 1 is marked by a beveled corner or dot.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | ENABLE | Active-low logic-enable input; drive low to assert OUT after 150ns; high impedance (±100nA leakage) with 0.4V/1.4V logic thresholds. |
| 2 | GND | Ground reference for all internal circuitry and output stage; must be connected directly to system ground plane. |
| 3 | IN | High-impedance monitor input (±15nA); compares voltage against 0.5V internal reference; requires external resistive divider for rail monitoring. |
| 4 | OUT | Active-low push-pull output; sinks up to 1mA (VCC ≥ 4.5V); asserts low when VIN > 0.5V and ENABLE is low; deasserts high within 16µs when condition fails. |
| 5 | CDELAY | Capacitor-adjustable delay node - unused in P version; internally bypassed; leave floating or tie to GND (no effect on timing). |
| 6 | VCC | Power supply input (1.5V–5.5V); requires local 0.1µF ceramic decoupling to GND; UVLO disables output below ~1.25V. |
Key Features
| Feature | Design Value |
|---|---|
| 150ns Enable Propagation Delay | Fixed, guaranteed timing from ENABLE low to OUT low - eliminates capacitor tolerance and temperature drift concerns in critical sequencing paths. |
| 0.5V Precision Monitor Threshold | 1.8% accuracy over -40°C to +125°C enables reliable detection of 1.2V, 1.8V, and 2.5V rails using simple, high-value resistor dividers (e.g., 1MΩ/1MΩ for 1.0V). |
| Ultra-Low Supply Current | 10µA typical ICC allows continuous monitoring in energy-constrained applications such as automotive telematics or portable medical sensors. |
| Push-Pull Active-Low Output | Eliminates external pullup resistor requirement and ensures defined logic state during power-up/down; compatible with standard microcontroller reset inputs. |
| Wide Operating Temperature Range | Full electrical specification from -40°C to +125°C qualifies MAX6896PAZT+ for under-hood automotive, industrial motor drives, and avionics subsystems. |
Applications
| Power-Supply Sequencing | Microcontroller Reset Supervision |

Use Value: Extends battery life by preventing deep discharge through precise 0.5V threshold detection and sub-10µA quiescent draw during sleep mode. |
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 |
|---|---|---|---|
| MAX6896AAZT+ | Capacitor-adjustable enable-to-output delay (tPROPA), not fixed 150ns; otherwise identical pinout, threshold, and output type. | Suitable where programmable delay (e.g., 1ms–1s) is required for staggered enable timing across multiple rails. | Select MAX6896AAZT+ if sequencing delay must be tuned per design; MAX6896PAZT+ preferred for deterministic, zero-capacitor timing. |
| TLV809EADBZR | Single-channel, active-low reset IC with fixed 140ms delay; no enable input; 2.93V fixed threshold; SOT23-3 package. | Limited to basic reset generation; lacks adjustable threshold, enable control, and sequencing capability. | Choose TLV809EADBZR only for simple, cost-sensitive reset-only use cases without sequencing or low-voltage monitoring needs. |
Compared with MAX6896AAZT+, MAX6896PAZT+ trades delay flexibility for timing precision and layout simplicity; compared with TLV809EADBZR, it offers full sequencing control, sub-1V monitoring, and active enable gating - making it suitable for complex multi-rail embedded systems rather than basic reset functions.

FAQ
What is the function of the CDELAY pin on MAX6896PAZT+?
The CDELAY pin on MAX6896PAZT+ is unused in the P-version device. Unlike A-version parts, MAX6896PAZT+ employs a fixed 150ns enable-to-output propagation delay and does not use external capacitance for timing. The pin may be left floating or tied to GND with no functional impact - it is not internally connected to the delay circuitry.
Does MAX6896PAZT+ support monitoring of a 1.2V supply rail?
Yes, MAX6896PAZT+ supports monitoring of a 1.2V rail using an external resistive divider. With its fixed 0.5V input threshold and ±15nA input leakage, a 2.4:1 divider (e.g., R1 = 1.2MΩ, R2 = 500kΩ) scales 1.2V down to exactly 0.5V at the IN pin, enabling accurate, low-error detection across temperature.
What is the maximum sink current capability of the MAX6896PAZT+ output?
The MAX6896PAZT+ push-pull output can sink up to 1mA while maintaining VOL ≤ 0.4V when VCC ≥ 4.5V, and up to 0.5mA at VOL ≤ 0.3V when VCC ≥ 2.25V. This allows direct interfacing with standard CMOS reset inputs or driving small MOSFET gates without additional buffering.
Is MAX6896PAZT+ qualified for automotive applications?
While MAX6896PAZT+ itself is not AEC-Q100 qualified, it belongs to the MAX6896 family whose A-grade variants (e.g., MAX6896AAZT/V+) are AEC-Q100 qualified. MAX6896PAZT+ shares identical die, package, and operating specifications (-40°C to +125°C), but qualification documentation applies only to designated /V+ suffix parts.
How does the enable logic work on MAX6896PAZT+?
MAX6896PAZT+ features an active-low ENABLE input: the output (OUT) asserts low only when both conditions are met - IN voltage exceeds 0.5V *and* ENABLE is driven low. If ENABLE is high, OUT remains high regardless of IN voltage. This allows precise software-controlled sequencing via MCU GPIO.
