Product details
Overview
MAX8216MJD from Maxim Integrated is a precision quad-supply voltage monitor IC with five integrated comparators - four dedicated to ±5V and ±15V rails, and one auxiliary comparator for programmable overvoltage/undervoltage detection. It features on-chip 1.24V reference (±1% initial accuracy), built-in hysteresis, open-drain outputs, and operates from 2.7V to 11V supply. Designed for high-reliability industrial and military systems, it delivers ±1.5% trip accuracy across -55°C to +125°C.
For engineers reviewing the MAX8216MJD datasheet, MAX8216MJD pinout, MAX8216MJD application, or MAX8216MJD equivalent, this device serves as a drop-in solution for ±15V supply monitoring in harsh-environment microprocessor supervision, where wide temperature range, low quiescent current (250µA max), and internal hysteresis eliminate external components.
Technical Context
The MAX8216MJD integrates five independent comparators: four fixed-threshold comparators for +5V, -5V, +15V, and -15V monitoring, each with ±1.5% accuracy over temperature; and one auxiliary comparator with externally accessible noninverting input (DIN) tied internally to the 1.24V reference. All outputs are open-drain, requiring external pull-ups and enabling wire-OR configurations.
Its internal 1.24V reference exhibits ±1% initial accuracy and <15 ppm/°C tempco; supply current remains ≤250µA across -55°C to +125°C; and built-in hysteresis eliminates need for external feedback resistors. The device supports undervoltage/overvoltage detection via resistor-divider programming at DIN, with typical hysteresis of 16mV.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8215MJD | Monitors ±12V instead of ±15V; identical pinout, package, and temperature grade | Suitable only where system uses ±12V analog rails-not interchangeable without redesigning rail connections | Select MAX8215MJD only for legacy ±12V systems; MAX8216MJD required for ±15V compliance. |
| TL7705ACD | Single +5V supervisor (no ±15V support); no auxiliary comparator; SO-8 package; 0°C to +70°C only | Limited to basic µP reset; cannot supervise dual-polarity or programmable rails | Use TL7705ACD only for cost-sensitive commercial +5V-only applications-not for extended temp or multi-rail monitoring. |
Compared with MAX8215MJD, MAX8216MJD provides ±15V rail compatibility essential for modern precision analog systems, while TL7705ACD lacks multi-rail capability, temperature range, and auxiliary functionality-making MAX8216MJD the sole qualified option for high-reliability ±15V supervision.

FAQ
What is the operating temperature range of the MAX8216MJD?
The MAX8216MJD is specified for continuous operation from -55°C to +125°C. This extended range is validated in its 14-pin CERDIP package and makes it suitable for aerospace, defense, and oilfield applications where ambient conditions exceed commercial or industrial limits. All electrical parameters-including trip accuracy, reference stability, and supply current-are guaranteed across this full range.
Does the MAX8216MJD require external hysteresis components?
No, the MAX8216MJD includes built-in hysteresis on all five comparators. Each dedicated comparator has 1.25–2.25% hysteresis, and the auxiliary comparator provides ~16mV typical hysteresis. This eliminates the need for external feedback resistors, simplifying design and improving noise immunity-especially critical in high-vibration or EMI-prone environments where the MAX8216MJD is commonly deployed.
Can the MAX8216MJD monitor a supply that also powers its own VDD pin?
Yes, the MAX8216MJD supports monitoring its own VDD supply using the +5V comparator and auxiliary comparator in combination-as shown in Figure 4 of the datasheet. Its outputs remain functional down to 0.8V VDD, enabling robust undervoltage/overvoltage detection even during brownout conditions. This capability is frequently used in self-powered reset circuits for microprocessors and FPGAs.
What is the function of the DIN and DOUT pins on the MAX8216MJD?
DIN is the noninverting input of the auxiliary comparator, referenced internally to the 1.24V bandgap reference. DOUT is its open-drain output. Together, they enable user-programmable overvoltage or undervoltage detection-for example, by connecting a resistor divider from a target rail to DIN. This allows customization beyond the four fixed rails, making the MAX8216MJD adaptable to nonstandard supply voltages without changing the IC.
Is the MAX8216MJD pin-compatible with other devices in the MAX8215/MAX8216 family?
Yes, all MAX8215 and MAX8216 variants-including MAX8216MJD-share identical 14-pin pinouts across DIP, SO, and CERDIP packages. The only functional difference is rail assignment: pins 5 and 6 monitor +12V/-12V in MAX8215, but +15V/-15V in MAX8216. Therefore, MAX8216MJD is a direct replacement for MAX8215MJD only when the system uses ±15V rails and the PCB layout accommodates that voltage range.
