Product details
Overview
AP4410BECHN from ABLIC is a dual-channel voltage detector IC with integrated P- and N-channel MOSFET power switches, operating from 1.2 V to 5.5 V supply, consuming 26 nA per channel, featuring ±35 mV detection accuracy, and supporting -40°C to +85°C operation for system-level power sequencing in portable electronics.
For engineers reviewing the AP4410BECHN datasheet, AP4410BECHN pinout, AP4410BECHN application, or AP4410BECHN equivalent, key selection criteria include dual-threshold detection (2.5 V / 3.1 V high, 2.0 V / 3.0 V low), open-drain/push-pull output configuration, WLCSP-20 package compatibility, and ultra-low quiescent current for battery-sensitive designs.
Technical Context
The AP4410BECHN integrates two independent voltage detection channels with programmable high/low thresholds, each driving a dedicated P- and N-channel MOSFET switch pair for controlled power path enable/disable. Its detection logic supports simultaneous monitoring of two different supply rails with independent reset or enable signaling.
It operates with a single 1.2–5.5 V supply and delivers rail-to-rail compatible output drive modes-open-drain for wired-OR configurations and push-pull for direct microcontroller interface-without external pull-up components required in open-drain mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 5.5 V - supports single-cell Li-ion, coin cell, and multi-rail embedded systems without level-shifting. |
| Channel Count | 2 independent detection channels - enables concurrent monitoring of core and I/O rails or primary/backup supplies. |
| Detection Thresholds (Ch1) | 2.5 V (high), 2.0 V (low) - precise reset assertion for 2.5 V logic domains with hysteresis margin. |
| Detection Thresholds (Ch2) | 3.1 V (high), 3.0 V (low) - tight 100 mV window ideal for 3.3 V supply brown-out detection. |
| Quiescent Current | 26 nA per channel - extends battery life in always-on monitoring applications such as IoT endpoint wake-up circuits. |
| Detection Accuracy | ±35 mV - ensures reliable trip-point repeatability across temperature and process variation. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and consumer-grade portable equipment environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector with integrated MOSFET switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP4410AECHJ | Ch1 high/low thresholds: 2.5 V / 2.0 V; Ch2: 2.7 V / 2.65 V - tighter Ch2 hysteresis but lower Ch2 high threshold. | Suitable for systems requiring earlier Ch2 assertion at 2.7 V, e.g., legacy 2.8 V logic rails. | Select AP4410AECHJ if Ch2 must trigger before 3.1 V, accepting reduced margin against 3.3 V rail noise. |
| AP4405AENMH | Single-channel device; thresholds 3.0 V / 2.5 V; HWQFN-16 package; 10 nA current. | Applicable where only one monitored rail exists and larger footprint is acceptable. | Choose AP4405AENMH for cost-sensitive, single-rail designs where WLCSP size and dual-channel capability are unnecessary. |
Compared with AP4410AECHJ and AP4405AENMH, the AP4410BECHN uniquely balances dual-channel flexibility with 3.1 V/3.0 V second-channel thresholds ideal for modern 3.3 V systems, while maintaining ultra-low power and minimal footprint-making it optimal for next-generation compact, multi-rail portable electronics.

FAQ
What is the exact detection threshold configuration of AP4410BECHN?
The AP4410BECHN features two independent detection channels: Channel 1 triggers high at 2.5 V and low at 2.0 V; Channel 2 triggers high at 3.1 V and low at 3.0 V. These fixed thresholds are factory-trimmed and specified with ±35 mV accuracy across -40°C to +85°C, eliminating need for external resistor networks or calibration.
Does AP4410BECHN support both open-drain and push-pull output modes?
Yes, AP4410BECHN supports configurable output drive: each output (OUT1 and OUT2) can be set to either open-drain or push-pull via dedicated SEL1/SEL2 pins. This allows flexible interfacing with microcontrollers, FPGAs, or other logic that requires active-low reset (open-drain) or rail-to-rail signaling (push-pull) without external components.
What package type and dimensions does AP4410BECHN use?
AP4410BECHN uses a 20-pin WLCSP package measuring 1.955 mm × 1.555 mm with 0.4 mm ball pitch. This ultra-compact, bottom-terminal package enables direct chip-scale mounting on dense PCBs and is compatible with standard reflow processes used for fine-pitch components.
Can AP4410BECHN drive external loads directly via its integrated MOSFETs?
Yes, AP4410BECHN integrates P- and N-channel MOSFETs per channel capable of switching up to 200 mA continuous load current. The MOSFETs are internally gated by detection logic, allowing AP4410BECHN to act as a self-contained load switch-no external drivers or gate resistors are needed for typical low-power rail enable/disable functions.
Is AP4410BECHN suitable for automotive applications?
No, AP4410BECHN is rated for -40°C to +85°C operation and is not AEC-Q200 qualified. It is intended for industrial, consumer, and portable electronics applications. For automotive use, ABLIC offers separate AEC-Q200 qualified variants such as the S-1909x series, which differ in qualification, packaging, and screening-not the AP4410BECHN.
