Product details

Overview

MAX8215CPD+ from Maxim Integrated is a precision 5-channel microprocessor voltage monitor IC featuring four dedicated comparators for +5V, −5V, +12V, and −12V supply rails 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 - all in a 14-pin plastic DIP package. Designed for embedded power supervision in industrial controllers and data-acquisition systems, it operates from 2.7V to 11V and draws ≤250µA over temperature.

For engineers reviewing the MAX8215CPD+ datasheet, MAX8215CPD+ pinout, MAX8215CPD+ application, or MAX8215CPD+ equivalent, key selection considerations include its ±1.25% +5V trip accuracy, built-in hysteresis eliminating external resistors, independent open-drain outputs enabling wire-OR configurations, and ability to monitor its own VDD supply down to 0.8V - critical for robust reset generation in low-voltage microprocessor systems.

Technical Context

The MAX8215CPD+ implements five independent comparators: four fixed-threshold channels (+5V, −5V, +12V, −12V) with ±1.25% (for +5V) or ±1.5% (for others) accuracy, and one auxiliary comparator (DIN/DOUT) whose noninverting input is externally accessible while its inverting input connects internally to the 1.24V reference. All outputs are open-drain, requiring external pull-ups and supporting wired-AND logic.

Its internal 1.24V reference exhibits ±1% initial accuracy and <15ppm/°C tempco; supply current remains ≤250µA across −40°C to +85°C (for extended-grade variants) and down to VDD = 2.7V. The device supports undervoltage/overvoltage detection via resistor-divider programming at DIN, with hysteresis of 1.25–2.25% and typical 16mV hysteresis voltage.

Key Specifications

Parameter	Value and Actual Design Meaning
+5V Trip Accuracy	±1.25% - ensures reliable microprocessor reset activation within tight voltage tolerance during brownout conditions.
−5V/+12V/−12V Trip Accuracy	±1.5% - provides consistent monitoring of auxiliary analog and digital supply rails in mixed-signal systems.

−12V (Pin 6)	−12V rail monitor input	Dedicated input for −12V supply; referenced to GND; trip threshold −12.904V to −13.566V (±1.5%).
DIN (Pin 7)	Auxiliary comparator noninverting input	Externally accessible input for programmable voltage monitoring; inverting input tied to 1.24V reference.
PGND (Pin 8)	Power ground	Separate ground pin for VDD bypassing; improves noise immunity and reference stability.
DOUT (Pin 9)	Auxiliary comparator output	Open-drain output; requires external pull-up; used for custom over/undervoltage detection or reset delay circuits.
OUT1 (Pin 10)	+5V comparator output	Open-drain output active-low when +5V falls below trip threshold; enables direct µP reset assertion.
OUT2 (Pin 11)	−5V comparator output	Open-drain output active-low when −5V rises above negative trip threshold (i.e., undervoltage condition).
OUT3 (Pin 12)	+12V comparator output	Open-drain output active-low when +12V falls below trip threshold; supports multi-rail fault signaling.
OUT4 (Pin 13)	−12V comparator output	Open-drain output active-low when −12V rises above negative trip threshold; complements OUT2 for bipolar rails.
VREF (Pin 1)	Internal reference output	Provides 1.24V ±1% reference for external circuitry or resistor-divider networks feeding DIN.

Key Features

Feature	Design Value
Five integrated comparators	Four fixed-rail monitors (+5V/−5V/+12V/−12V) plus one programmable auxiliary channel (DIN/DOUT) - reduces BOM count and board space vs. discrete solutions.
On-chip 1.24V reference	±1% initial accuracy and <15ppm/°C tempco - eliminates need for external reference IC while maintaining precision across temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microprocessor voltage monitor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX6821ESA+	Single +3.3V/+5V monitor with watchdog timer and manual reset; no negative rail support; 8-pin SO package.	Limited to unipolar supplies; lacks auxiliary comparator and reference output; intended for simpler, lower-pin-count designs.	Select when only +3.3V/+5V supervision is required and board space is constrained; not suitable for ±12V or programmable monitoring.
TL7705ACDR	Single +5V supervisor IC with 4.63V threshold, no reference output, no hysteresis control, and push-pull output.	Monitors only +5V; no support for negative rails, auxiliary detection, or open-drain flexibility; higher supply current (~1mA).	Choose for cost-sensitive, single-rail applications where open-drain outputs and multi-rail coverage are unnecessary.

Compared with MAX6821ESA+ and TL7705ACDR, the MAX8215CPD+ delivers unique value through simultaneous ±5V/±12V monitoring, a programmable fifth comparator, on-chip 1.24V reference, and ultra-low 250µA supply current - making it the only option capable of consolidated, precision, multi-rail supervision in compact industrial and communications equipment.

FAQ

What is the operating temperature range for the MAX8215CPD+?

The MAX8215CPD+ is rated for commercial temperature operation from 0°C to +70°C. Its electrical specifications - including ±1.25% +5V trip accuracy, 1.24V reference stability, and ≤250µA supply current - are guaranteed across this full range. This makes the MAX8215CPD+ suitable for indoor industrial equipment and consumer-grade embedded systems where ambient thermal stress is moderate.

Can the MAX8215CPD+ monitor its own VDD supply?

Yes, the MAX8215CPD+ can monitor its own VDD supply using the +5V comparator and auxiliary comparator (DIN/DOUT). As documented in Figure 4 and Figure 7 of the datasheet, the +5V input can be connected to VDD through a resistor divider to detect undervoltage, while DIN can be configured for overvoltage detection. The device operates down to VDD = 0.8V, ensuring reliable reset assertion even during severe brownout conditions - a key feature of the MAX8215CPD+.

Does the MAX8215CPD+ require external hysteresis components?

No, the MAX8215CPD+ does not require external hysteresis components. All five comparators integrate factory-trimmed hysteresis - 1.25–2.25% for dedicated channels and ~16mV for the auxiliary comparator. This eliminates the need for external feedback resistors, reduces PCB area, and ensures consistent noise immunity across temperature and voltage. The built-in hysteresis is a defining characteristic of the MAX8215CPD+ design.

What is the function of the PGND pin on the MAX8215CPD+?

The PGND (Pin 8) on the MAX8215CPD+ is a dedicated power ground terminal used exclusively for bypassing VDD with a 0.1µF capacitor. It is separate from the analog GND (Pin 2) to minimize noise coupling into the reference and comparator inputs. Proper connection of the bypass capacitor between VDD (Pin 14) and PGND (Pin 8) is mandatory for stable operation of the internal 1.24V reference - a requirement explicitly stated in the MAX8215CPD+ datasheet.

How does the auxiliary comparator (DIN/DOUT) differ from the four dedicated comparators in the MAX8215CPD+?

The auxiliary comparator in the MAX8215CPD+ differs fundamentally: its noninverting input (DIN) is externally accessible for user-defined voltage monitoring, 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 MAX8215CPD+ to support programmable overvoltage/undervoltage detection, time-delayed reset generation, and custom trip-point configurations - functionality unavailable in the fixed-rail channels.
