Product details
Overview
MAX8216EPD+ from Maxim Integrated is a precision 5-channel voltage monitor IC designed for microprocessor supply supervision, featuring four dedicated comparators for ±5V and ±15V rails plus one auxiliary comparator for programmable over/undervoltage detection; includes on-chip 1.24V reference (±1% initial accuracy), built-in hysteresis, open-drain outputs, and operates from 2.7V to 11V supply with ≤250µA max current over temperature.
For engineers reviewing the MAX8216EPD+ datasheet, MAX8216EPD+ pinout, MAX8216EPD+ application, or MAX8216EPD+ equivalent, this page delivers verified electrical parameters, exact pin functions, real-world use cases in industrial controllers and portable instruments, and validated alternative parts for supply chain continuity and design flexibility.
Technical Context
The MAX8216EPD+ integrates five independent comparators: four fixed-threshold channels for +5V (±1.25%), −5V (±1.5%), +15V (±1.5%), and −15V (±1.5%) monitoring, plus an auxiliary comparator with externally accessible noninverting input (DIN) referenced to the internal 1.24V bandgap. All outputs are open-drain, requiring external pull-ups.
Hysteresis is fully integrated-no external resistors needed-with typical hysteresis of 16mV and tempco of 0.005%/°C for ±15V/±12V/−5V inputs. The device supports supply monitoring down to 0.8V VDD and maintains stable reference regulation across −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| +5V trip level | 4.500V to 4.657V (±1.25% accuracy at TA = +25°C; enables precise µP reset initiation) |
| ±15V trip level | +15V: 12.904V–13.566V; −15V: −12.904V–−13.566V (±1.5% accuracy; supports high-voltage industrial rail monitoring) |
| Reference voltage | 1.24V ±1% initial accuracy, ±15ppm/°C tempco (stable reference for auxiliary comparator threshold setting) |
| Supply current | ≤250µA over full −40°C to +85°C range (enables low-power system supervision without burdening supply) |
| Supply voltage range | 2.7V to 11V (supports operation from single Li-ion battery up to multi-rail industrial supplies) |
| Comparator response time | 20µs with 30mV overdrive (ensures fast fault detection for critical power sequencing) |
| Output voltage low | 0.11V max at ISINK = 2mA, VDD = 5V (guarantees solid logic-low assertion for reset or alert signaling) |
Pinout & Package
MAX8216EPD+ uses a 14-pin plastic DIP package (0.300" wide, JEDEC MS-001), lead-free compliant (indicated by '+' suffix), rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VREF) | Internal reference output | Provides 1.24V ±1% reference for auxiliary comparator; requires no external components |
| 2 (GND) | Analog ground | Must be connected to PGND; separates signal reference from power return path |
| 3 (+5V) | +5V supply input | Dedicated comparator input for +5V rail monitoring; tolerates up to +20V transient |
| 4 (−5V) | −5V supply input | Dedicated comparator input for −5V rail; ±1.5% trip accuracy; withstands ±50V absolute max |
| 5 (+15V) | +15V supply input | MAX8216-specific input (replaces +12V on MAX8215); trip level 12.904V–13.566V |
| 6 (−15V) | −15V supply input | MAX8216-specific input (replaces −12V on MAX8215); trip level −12.904V–−13.566V |
| 7 (DIN) | Auxiliary comparator noninverting input | Externally accessible node for custom voltage monitoring; referenced internally to VREF |
| 8 (PGND) | Power-supply ground | Bypass VDD to this pin with 0.1µF capacitor; separate from GND to reduce noise coupling |
| 9 (DOUT) | Auxiliary comparator open-drain output | Drives reset, alert, or enable signals; requires external pull-up resistor ≥2.7kΩ |
| 10–13 (OUT1–OUT4) | Dedicated comparator open-drain outputs | OUT1=+5V, OUT2=−5V, OUT3=+15V, OUT4=−15V; each independently configurable for wire-OR logic |
| 14 (VDD) | Positive supply input | 2.7V–11V operating range; bypass to PGND with 0.1µF ceramic capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Five integrated comparators | Four fixed-rail (±5V, ±15V) + one programmable auxiliary channel eliminates need for discrete comparators and external references |
| Built-in hysteresis | 16mV typical hysteresis prevents noise-induced oscillation at trip points-no external feedback resistors required |
| On-chip 1.24V reference | ±1% initial accuracy and ±15ppm/°C tempco ensures stable thresholds for auxiliary comparator across temperature |
| Open-drain outputs | All five outputs support wired-OR configuration and LED driving; compatible with mixed-voltage systems (VDD = 2.7–11V) |
| Low quiescent current | ≤250µA max over −40°C to +85°C enables always-on supervision in battery-powered portable instruments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8215EPD+ | Monitors ±5V and ±12V instead of ±15V; identical pinout, package, and feature set otherwise | Suitable only where ±12V rails exist; not interchangeable in ±15V systems without redesign | Select when legacy ±12V infrastructure is used and no ±15V monitoring is required |
| TPS3808G18DBVR | Single-channel, adjustable threshold (0.405V–5.8V); no built-in reference or multi-rail capability; 1.8V–6.5V supply | Requires external resistor dividers and reference for multi-rail monitoring; lacks dedicated ±15V trip points | Choose for cost-sensitive, single-rail applications where programmability outweighs integration |
Compared with MAX8216EPD+, MAX8215EPD+ offers identical form-factor and supervision architecture but targets ±12V systems, while TPS3808G18DBVR trades multi-rail integration for lower unit cost and wider adjustability-neither is pin-compatible, and both require PCB changes for substitution.

FAQ
What is the operating temperature range for the MAX8216EPD+?
The MAX8216EPD+ is specified for −40°C to +85°C operation, making it suitable for industrial and extended-temperature environments. This grade ('E' suffix) ensures guaranteed performance across the full range, including comparator accuracy, reference stability, and supply current limits-all validated per Maxim's Electrical Characteristics table.
Does the MAX8216EPD+ require external hysteresis resistors?
No, the MAX8216EPD+ includes fully integrated hysteresis on all five comparators-no external resistors are needed. Typical hysteresis is 16mV with 0.005%/°C tempco, eliminating noise-induced output oscillation near trip thresholds and simplifying board layout versus discrete solutions.
Can the MAX8216EPD+ monitor its own VDD supply?
Yes, the MAX8216EPD+ can monitor its own VDD supply using the +5V comparator and auxiliary comparator (DIN/DOUT) in combination, as shown in Figure 4 and Figure 7 of the datasheet. It operates down to 0.8V VDD, enabling reliable undervoltage detection even during deep brownout conditions.
What is the function of the PGND pin on the MAX8216EPD+?
The PGND (Pin 8) on the MAX8216EPD+ is the dedicated power-supply ground terminal, distinct from analog GND (Pin 2). It must be bypassed to VDD with a 0.1µF ceramic capacitor and serves as the return path for internal power circuitry-separating noisy power currents from sensitive analog reference and comparator paths to ensure accuracy.
Is the MAX8216EPD+ pin-compatible with the MAX8215 series?
Yes, the MAX8216EPD+ is pin-compatible with the MAX8215EPD+ and all other MAX8215/MAX8216 variants in the same package (14-pin PDIP/SO/CERDIP). Pin functions match exactly-including VREF, DIN, DOUT, and all dedicated rail inputs-but the +12V/−12V pins on MAX8215 correspond to +15V/−15V on MAX8216, so external circuitry must match the target rail voltages.
