Product details
Overview
MAX8215ESD+ from Maxim Integrated is a precision 5-channel microprocessor voltage monitor IC featuring four dedicated comparators for +5V, −5V, +12V, and −12V supply monitoring, plus one auxiliary comparator for programmable overvoltage/undervoltage detection. It integrates an internal 1.24V reference (±1% initial accuracy), on-chip hysteresis, and open-drain outputs. Designed for industrial embedded systems requiring reliable power-good signaling and reset generation under wide temperature conditions (−40°C to +85°C).
For engineers reviewing the MAX8215ESD+ datasheet, MAX8215ESD+ pinout, MAX8215ESD+ application, or MAX8215ESD+ equivalent, key selection considerations include its ±1.25% +5V trip accuracy, 250µA max supply current over temperature, −40°C to +85°C extended industrial grade rating, and compatibility with SO-14 lead-free packaging per RoHS.
Technical Context
The MAX8215ESD+ implements five independent comparators in a single monolithic IC: four fixed-threshold channels for standard supply rails (+5V, −5V, +12V, −12V) and one uncommitted auxiliary channel (DIN/DOUT) with internal 1.24V reference connection. All outputs are open-drain, enabling wired-OR configurations and LED drive without external level-shifting.
Its internal hysteresis eliminates external resistor networks for noise immunity, while the 1.24V reference supports accurate trip-point derivation via external resistor dividers on DIN. The device operates from 2.7V to 11V VDD and maintains valid output states down to 0.8V supply-critical for self-monitoring applications where VDD is the monitored rail.
Key Specifications

|---|---|
| +5V Trip Accuracy | ±1.25% - ensures precise brown-out detection at nominal 4.657V threshold with minimal calibration overhead |
| −5V / ±12V Trip Accuracy | ±1.5% - guarantees consistent fault detection across negative and higher positive rails |
| Supply Current | 250µA max over −40°C to +85°C - enables low-power system monitoring without burdening standby supplies |
| Reference Voltage | 1.24V ±1% initial accuracy - provides stable, traceable basis for auxiliary comparator trip-point design |
| Hysteresis Voltage | 16mV typical - suppresses noise-induced chatter near trip thresholds without external components |
| Operating Voltage Range | 2.7V to 11V - supports direct monitoring of diverse logic and analog supply domains |

Pinout & Package
MAX8215ESD+ is housed in a 14-pin SO (Small Outline) package, RoHS-compliant and lead-free (indicated by '+' suffix), with 1.27mm pitch and JEDEC MS-012AC footprint. Thermal performance supports 667mW continuous dissipation at +70°C, derating 8.33mW/°C above ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VREF) | Internal reference output | Provides 1.24V ±1% reference for auxiliary comparator; requires no external buffering for typical divider networks |
| 2 (GND) | Analog ground | Must be connected to PGND (Pin 8); separates signal reference from power return path |
| 3 (+5V) | +5V supply input | Dedicated comparator input; monitors +5V rail with ±1.25% accuracy and built-in hysteresis |
| 4 (−5V) | −5V supply input | Dedicated comparator input; monitors −5V rail with ±1.5% accuracy and built-in hysteresis |

| 6 (−12V) | −12V supply input | Dedicated comparator input; monitors −12V rail with ±1.5% accuracy (MAX8215 only) |
| 7 (DIN) | Auxiliary comparator noninverting input | Accepts externally divided voltage; inverting input tied internally to VREF for programmable OV/UV detection |
| 8 (PGND) | Power-supply ground | Bypass VDD (Pin 14) directly to this pin with 0.1µF capacitor; critical for reference stability in noisy environments |
| 9 (DOUT) | Auxiliary comparator open-drain output | Drives reset, alarm, or status lines; requires external pull-up; supports 2mA sink capability |
| 10–13 (OUT1–OUT4) | Dedicated comparator open-drain outputs | OUT1 = +5V, OUT2 = −5V, OUT3 = +12V, OUT4 = −12V; each independently configurable for system-level fault reporting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor voltage monitor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8216ESD+ | Monitors ±15V instead of ±12V; identical pinout, reference, and auxiliary comparator architecture | Required when system uses ±15V analog supplies rather than ±12V; not interchangeable without circuit revision | Select MAX8216ESD+ only if ±15V rail monitoring is needed; otherwise MAX8215ESD+ is optimal for ±12V systems |
| TPS3808G33DBVR | Single-channel 3.3V supervisor with 200ms reset delay; no multi-rail or auxiliary comparator capability | Suitable only for basic 3.3V-only reset generation; lacks rail-specific monitoring or programmable OV/UV detection | Use TPS3808G33DBVR for simple single-rail applications; MAX8215ESD+ required for multi-rail, diagnostic, or custom threshold needs |
Compared with MAX8216ESD+, the MAX8215ESD+ provides tighter +5V accuracy (±1.25% vs ±1.5%) and matches ±12V systems without redesign. Versus TPS3808G33DBVR, it delivers five independent monitoring channels and programmable auxiliary detection-enabling full-system power integrity coverage in one SO-14 device.

FAQ
What is the operating temperature range for MAX8215ESD+?
The MAX8215ESD+ is rated for −40°C to +85°C operation, making it suitable for extended industrial environments. This range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet. The 'E' grade designation in MAX8215ESD+ explicitly denotes this extended temperature capability, distinct from the commercial-grade 'C' version (0°C to +70°C). All electrical specifications-including trip accuracy, supply current, and reference stability-are guaranteed across this full range.
Does MAX8215ESD+ require external hysteresis components?
No, MAX8215ESD+ does not require external hysteresis components. The device integrates factory-trimmed hysteresis into all five comparators, with a typical value of 16mV. This eliminates the need for external feedback resistors and simplifies PCB layout. The hysteresis is implemented internally and contributes to the specified ±1.25% and ±1.5% trip accuracy tolerances. External resistor networks are only needed for the auxiliary comparator (DIN) to set custom trip points-not for hysteresis.
Can MAX8215ESD+ monitor its own VDD supply?
Yes, MAX8215ESD+ can monitor its own VDD supply using the +5V comparator and auxiliary comparator in combination. Figure 4 in the datasheet shows a validated circuit where the +5V input monitors VDD for undervoltage, while the DIN/DOUT channel detects overvoltage via a resistor divider. The device maintains valid open-drain outputs down to 0.8V VDD, enabling operation through deep brownout. No additional bypassing beyond the recommended 0.1µF capacitor is required for this self-monitoring function.
What is the purpose of the PGND pin (Pin 8) on MAX8215ESD+?
The PGND (Power Ground) pin (Pin 8) on MAX8215ESD+ serves as the dedicated return path for the VDD supply bypass capacitor and isolates power-ground noise from the analog ground (GND, Pin 2). Per the datasheet's "Power-Supply Bypassing and Grounding" section, VDD must be bypassed directly to PGND with a 0.1µF capacitor. This separation prevents switching noise from corrupting the internal 1.24V reference and comparator thresholds. GND (Pin 2) connects to PGND but is intended for analog reference routing, not bulk decoupling.
How does the auxiliary comparator (DIN/DOUT) differ from the four dedicated comparators in MAX8215ESD+?
The auxiliary comparator in MAX8215ESD+ differs fundamentally: its noninverting input (DIN) is brought out to a pin for external voltage connection, while its inverting input is hardwired to the internal 1.24V reference. In contrast, the four dedicated comparators have fixed internal thresholds for +5V, −5V, +12V, and −12V. This architecture allows the auxiliary comparator to perform programmable overvoltage or undervoltage detection on any rail-using external resistors to scale the input-whereas the dedicated comparators provide factory-calibrated, rail-specific monitoring without external components.
