Product details
Overview
ADCMP370AKSZ-REEL7 from Analog Devices is a general-purpose comparator with open-drain output, 22 V input/output voltage tolerance, 9 mV max input offset voltage, and 4 µA supply current-designed for battery management systems and low-voltage portable electronics requiring rail-to-rail common-mode input range and operation from 2.25 V to 5.5 V.
For engineers reviewing the ADCMP370AKSZ-REEL7 datasheet, ADCMP370AKSZ-REEL7 pinout, ADCMP370AKSZ-REEL7 application, or ADCMP370AKSZ-REEL7 equivalent, key selection criteria include its 22 V tolerant inputs/outputs, ultra-low quiescent current, SC70-5 package footprint, and compatibility with high-side voltage detection in single-supply systems.
Technical Context
The ADCMP370AKSZ-REEL7 implements a precision comparator core with rail-to-rail input stage and open-drain NMOS output capable of sinking up to 1.2 mA while tolerating 22 V at OUT. Its input bias current (50 nA typ) and offset current (150 nA max) support high-impedance sensing nodes without significant error contribution.
Propagation delay is specified at 5 µs (10 mV overdrive) and 2 µs (100 mV overdrive), with stable performance across −40°C to +85°C. The device's 146°C/W θJA thermal impedance and SC70 package enable compact placement in space-constrained portable designs.
Key Specifications

Applications
| Battery Voltage Monitor | Power-Good Detector |
|---|---|
Use Scenario: Monitoring lithium-ion cell voltage during charging/discharging to trigger under-voltage lockout or over-voltage protection. IC Role / Device Role / Timing Role: Comparator compares cell voltage against precision reference; open-drain output drives enable/disable logic of protection IC or charger controller. Use Value: 22 V input tolerance allows direct connection to multi-cell packs; 4 µA current minimizes parasitic drain on resting battery. | Use Scenario: Validating regulated 3.3 V or 5 V supply stability before enabling downstream digital subsystems. IC Role / Device Role / Timing Role: Compares supply rail to internal or external reference; asserts open-drain "PGOOD" signal after delay or hysteresis filtering. Use Value: Rail-to-rail input accepts full supply range; propagation delay <5 µs ensures fast fault response without false triggering. |
| Low-Power Sensor Threshold Detector | Portable Equipment Wake-Up Circuit |
Use Scenario: Detecting motion, light, or temperature thresholds from high-impedance analog sensors in wearables or IoT nodes. IC Role / Device Role / Timing Role: Converts sensor output to digital event signal; output pulls low to wake microcontroller via interrupt pin. Use Value: 50 nA input bias avoids loading high-Z sensor outputs; 9 mV offset ensures sub-10 mV detection resolution. | Use Scenario: Waking a sleeping MCU when battery voltage rises above recharge threshold or external button press is detected. IC Role / Device Role / Timing Role: Acts as level-sensitive wake source; open-drain output interfaces directly to MCU reset/interrupt pin with flexible pull-up voltage. Use Value: 22 V tolerant OUT allows wake signal generation at system-level voltage (e.g., 12 V adapter presence), independent of MCU I/O voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDCKR | Push-pull output, 360 nA supply current, 10 mV offset, 5.5 V max VCC, same SC70-5 package. | Lacks 22 V input/output tolerance; unsuitable for high-side sensing beyond VCC. | Select when push-pull drive is required and all signals remain within VCC domain. |
| MAX9021AXK+T | Open-drain output, 1 µA supply current, 5 mV offset, 5.5 V max VCC, SC70-5 package. | Lower supply current but no >VCC input tolerance; limited to single-supply rail-referenced sensing. | Select when ultra-low power dominates and voltage sensing stays within VCC range. |
Compared with TLV3691IDCKR and MAX9021AXK+T, ADCMP370AKSZ-REEL7 uniquely supports 22 V tolerant inputs and outputs while maintaining 4 µA quiescent current-making it the only option among the three for direct high-voltage battery or adapter presence detection without external components.

FAQ
What is the maximum input voltage the ADCMP370AKSZ-REEL7 can tolerate?
The ADCMP370AKSZ-REEL7 supports input voltages from −0.3 V to +25 V on both IN+ and IN− pins, independent of VCC. This 22 V tolerance (relative to GND) enables direct connection to battery packs, adapter rails, or other voltage sources exceeding the supply rail-eliminating need for external clamping or attenuation networks in ADCMP370AKSZ-REEL7 designs.
Does the ADCMP370AKSZ-REEL7 require an external pull-up resistor on its output?
Yes, the ADCMP370AKSZ-REEL7 features an open-drain output that must be pulled up externally to define the logic-high state. A resistor between 1 kΩ and 10 kΩ is recommended-small enough for reasonable rise time, large enough to limit power dissipation. The pull-up voltage may be as high as 22 V, enabling level translation beyond VCC in ADCMP370AKSZ-REEL7 applications.
What is the typical supply current of the ADCMP370AKSZ-REEL7 at 3.3 V?
At VCC = 3.3 V and TA = +25°C, the ADCMP370AKSZ-REEL7 draws 4 µA typical supply current, with a maximum of 7 µA across temperature and voltage range. This ultra-low quiescent current makes ADCMP370AKSZ-REEL7 ideal for always-on voltage monitoring in battery-powered devices where standby power budget is critical.
Can the ADCMP370AKSZ-REEL7 operate with a 2.25 V supply?
Yes, the ADCMP370AKSZ-REEL7 is fully specified from 2.25 V to 5.5 V. At 2.25 V, it maintains rail-to-rail common-mode input range, 9 mV max input offset, and functional open-drain output-enabling use in single-cell Li-ion (2.7–4.2 V) or alkaline (1.8–3.0 V) powered systems. Performance data including supply current and propagation delay are validated across this full ADCMP370AKSZ-REEL7 operating range.
What package type does the ADCMP370AKSZ-REEL7 use?
The ADCMP370AKSZ-REEL7 uses a 5-lead SC70 package (JEDEC MO-203-AA, Analog Devices KS-5), measuring 2.00 mm × 1.25 mm × 0.90 mm with 0.65 mm lead pitch. It is RoHS-compliant (indicated by the "Z" suffix) and optimized for automated assembly in space-constrained portable electronics-matching footprint requirements of ADCMP370AKSZ-REEL7 in high-volume manufacturing.
