Product details
Overview
ADCMP356YKSZ-REEL7 from Analog Devices is a precision comparator with integrated 0.6 V reference, noninverting input configuration, and push-pull active-high output stage. It operates from 2.25 V to 5.5 V supply, delivers 5 µs propagation delay, 15 mV hysteresis, and supports −40°C to +125°C operation in automotive voltage detector applications.
For engineers reviewing the ADCMP356YKSZ-REEL7 datasheet, ADCMP356YKSZ-REEL7 pinout, ADCMP356YKSZ-REEL7 application, or ADCMP356YKSZ-REEL7 equivalent, key selection criteria include its push-pull output drive capability, 22 V input tolerance, low 10 µA supply current, and SC70-4 package compatibility for space-constrained battery-monitoring systems.
Technical Context
The ADCMP356YKSZ-REEL7 implements a noninverting comparator architecture with an internal 0.6 V reference, enabling direct threshold detection without external reference components. Its push-pull output drives logic-high up to 0.8 × VCC at 500 µA source current and logic-low down to 0.4 V at 1.2 mA sink current.
Input structure tolerates up to 22 V independent of VCC, allowing direct high-side monitoring of battery or supply rails. Hysteresis is fixed at 15 mV (typ), and propagation delay remains stable across temperature (−40°C to +125°C) and supply voltage (2.25 V to 5.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.25 V to 5.5 V - supports single Li-ion or dual-cell battery systems and 3.3 V/5 V logic domains. |
| Input Voltage Range | 0 V to 22 V - enables direct monitoring of 12 V automotive batteries or industrial supplies without level-shifting. |
| Reference Voltage | 0.6 V ±21 mV (−40°C to +125°C) - provides stable trip point for resistor-divider-based voltage detection. |
| Propagation Delay | 5 µs - ensures timely response in power-good signaling and overvoltage lockout circuits. |
| Supply Current | 10 µA (typ) - minimizes quiescent power in always-on battery monitors and wake-up supervisors. |
| Hysteresis | 15 mV (typ) - suppresses noise-induced chatter on slowly varying inputs like battery discharge curves. |
| Output Type | Push-pull active-high - eliminates need for external pull-up resistors and reduces BOM count in microcontroller interface designs. |
Pinout & Package
ADCMP356YKSZ-REEL7 is housed in a 4-lead SC70 (KS-4) package - 2.20 mm × 1.35 mm footprint, 0.95 mm height, lead pitch 0.65 mm - optimized for ultra-compact portable and automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Noninverting Input | Accepts analog input up to 22 V; threshold comparison occurs when VIN exceeds internal 0.6 V reference. |
| GND (Pin 2) | Ground Reference | Return path for supply and signal; must be low-impedance to maintain reference accuracy and noise immunity. |
| OUT (Pin 3) | Digital Output | Push-pull driver capable of sourcing 500 µA or sinking 1.2 mA; directly interfaces with CMOS/TTL logic inputs. |
| VCC (Pin 4) | Power Supply | Supplies internal reference and output stage; decoupling capacitor required within 1 cm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 0.6 V Reference | Eliminates external reference IC or resistor divider, reducing component count and layout area in voltage monitor designs. |
| 22 V Input Tolerance | Allows direct connection to unregulated 12 V or 24 V rails without attenuation networks or protection diodes. |
| Push-Pull Output Stage | Provides rail-to-rail logic-compatible output swing without external pull-up, simplifying interface to MCUs and FPGAs. |
| −40°C to +125°C Operation | Validated performance across full automotive under-hood temperature range, supporting AEC-Q100-relevant use cases. |
| Low 10 µA Quiescent Current | Enables multi-year operation in coin-cell-powered asset trackers and IoT sensors requiring always-on supervision. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3011IDBVR | 0.2 V internal reference, open-drain output, 1.8 V to 5.5 V supply, 12 µA supply current | Lacks 22 V input tolerance; requires external pull-up; suited for low-voltage, low-power portable systems only | Select TLV3011IDBVR only if reference voltage < 0.6 V is acceptable and high-voltage input monitoring is unnecessary. |
| MAX9060ASA+ | 1.236 V internal reference, push-pull output, 2.5 V to 5.5 V supply, 15 µA supply current, no 22 V input rating | Higher reference voltage demands different resistor divider; not rated for >5.5 V input; limited to 85°C max ambient | Choose MAX9060ASA+ only for cost-sensitive consumer applications where extended temperature and high-voltage tolerance are not required. |
Compared with TLV3011IDBVR and MAX9060ASA+, ADCMP356YKSZ-REEL7 uniquely combines 22 V input tolerance, −40°C to +125°C operation, and push-pull drive in SC70-4 - making it the sole option for robust automotive or industrial voltage supervision where external components must be minimized and environmental stress is high.

FAQ
What is the output configuration of ADCMP356YKSZ-REEL7?
The ADCMP356YKSZ-REEL7 features a push-pull active-high output stage. This means it actively drives the output high (up to 0.8 × VCC at 500 µA source current) and low (down to 0.4 V at 1.2 mA sink current), eliminating the need for external pull-up resistors. Unlike the open-drain variants ADCMP350 and ADCMP354, ADCMP356YKSZ-REEL7 provides true rail-to-rail logic-compatible output swing.
Does ADCMP356YKSZ-REEL7 require an external reference voltage?
No, ADCMP356YKSZ-REEL7 integrates a precision 0.6 V reference internally. This reference is trimmed and temperature-compensated (30 ppm/°C typical), enabling direct use with resistor dividers to set custom thresholds - for example, detecting 3.0 V by using a 4:1 resistor ratio. No external reference IC or voltage divider for reference generation is needed.
Can ADCMP356YKSZ-REEL7 safely monitor a 12 V automotive battery?
Yes, ADCMP356YKSZ-REEL7 supports up to 22 V on the VIN pin regardless of VCC voltage, making it safe for direct connection to 12 V automotive battery rails. Its input structure is designed for high-voltage tolerance without external clamping or attenuation, and its −40°C to +125°C operating range aligns with under-hood environmental requirements.
What is the propagation delay specification for ADCMP356YKSZ-REEL7?
The ADCMP356YKSZ-REEL7 has a typical propagation delay of 5 µs, measured from VIN crossing the threshold (VTH) to the output transitioning fully (VTH − 100 mV). This value is specified across the full −40°C to +125°C temperature range and 2.25 V to 5.5 V supply range, ensuring consistent timing behavior in safety-critical supervision circuits.
Is hysteresis adjustable on ADCMP356YKSZ-REEL7?
No, ADCMP356YKSZ-REEL7 includes fixed internal hysteresis of 15 mV (typical). However, external positive feedback can be added to increase hysteresis - particularly useful for noisy signals - using two resistors as described in the datasheet's Applications Information section. The internal hysteresis alone suffices for most battery monitoring and power-supply supervision tasks.
