Product details
Overview
MAX14653EWC+T from Maxim Integrated is a high-current overvoltage protector IC with integrated 38mΩ (typ) n-channel MOSFET switch, fixed 15.5V ±3.3% internal OVLO threshold, and open-drain ACOK status flag. It protects downstream PMICs and application processors in portable power paths against input surges up to +80V and faults up to +28VDC, supporting continuous 4.5A load current in smartphones and tablets.
For engineers reviewing the MAX14653EWC+T datasheet, MAX14653EWC+T pinout, MAX14653EWC+T application, or MAX14653EWC+T equivalent, key selection criteria include its 15.5V trip point accuracy, 15ms startup debounce, thermal shutdown at +130°C, soft-start timing, and WLP package footprint compatibility with space-constrained mobile designs.
Technical Context
The MAX14653EWC+T implements a charge-pump–driven internal FET with precise voltage monitoring logic. Its OVLO comparator uses an internal 1.26V reference and fixed resistor divider to set 15.5V (±3.3%) trip level-no external components required when OVLO pin is grounded.
It features synchronized 15ms debounce and 30ms soft-start to prevent inrush-induced false trips, while ACOK asserts low only after VIN stabilizes between 2.5V and VOVLO. Thermal shutdown disables the FET at +130°C with 20°C hysteresis, and the device survives 80V transient surges per IEC 61000-4-2 (±8kV contact, ±15kV air-gap on IN).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| OVLO Threshold | 15.5V ±3.3% typical - enables robust protection for 12V/15V input rails without external adjustment. |
| RON (Typ) | 38mΩ at VIN = 5V, IOUT = 1A - minimizes conduction loss and thermal rise under 4.5A continuous load. |
| Continuous Current | 4.5A - supports high-power USB PD and fast-charging battery management systems. |
| Surge Immunity | +80V (2Ω series) - clamps transients from hot-plug events or adapter faults without latch-up. |
| ACOK Output | Open-drain, logic-compatible flag - signals stable supply to host processor after 15ms debounce and soft-start. |
| Operating Temp | -40°C to +85°C - qualified for extended industrial and consumer mobile operating environments. |
| Package | 12-bump WLP (1.29mm × 1.83mm) - enables ultra-compact placement adjacent to battery connectors or PMIC inputs. |
Pinout & Package
MAX14653EWC+T uses a 12-bump wafer-level package (WLP) measuring 1.29mm × 1.83mm with bottom-side solder bumps. Pin assignment follows standard top-view bump layout with GND, IN, OUT, ACOK, and OVLO terminals distributed across three rows.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A4, B4, C4 | GND | Power ground return path - all four pins must be connected together for optimal thermal and EMI performance. |
| A2, A3, B2 | OUT | Switched output node - connects to protected downstream circuitry (e.g., PMIC input); paralleled for current sharing. |
| B1 | ACOK | Open-drain status flag - pulled low by internal FET when VIN is stable within OVLO window; requires external pullup. |
| B3, C2, C3 | IN | Main input voltage rail - bypassed with 0.1µF ceramic capacitor; all three pins carry full input current. |
| C1 | OVLO | Overvoltage threshold select - grounded for 15.5V internal trip; accepts resistor divider for adjustable thresholds (4V–20V). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 38mΩ n-FET | Reduces power loss and board area vs. discrete FET + controller solutions; eliminates gate-drive complexity. |
| 15ms Startup Debounce | Prevents false turn-on during input ramp-up or noisy adapter connection, improving system boot reliability. |
| 30ms Soft-Start | Controls dV/dt at OUT to safely charge up to 1000µF output capacitance without triggering overcurrent shutdown. |
| 80V Surge Clamping | Withstands IEC 61000-4-2 level 4 transients on IN pin without external TVS, simplifying front-end protection design. |
| Thermal Shutdown + Hysteresis | Disables FET at +130°C junction temperature and re-enables only after cooling to +110°C, preventing thermal oscillation. |
Applications
| Smartphone Power Input Protection | Tablet PC Charging Path Guard |
|---|---|
|
Use Scenario: Protects application processor and PMIC from USB-C adapter overvoltage during fast charging or faulty wall adapters.

Use Scenario: Secures main battery charging path in dual-cell tablet designs where input surges may exceed 20V during adapter hot-swap. IC Role / Device Role / Timing Role: Primary overvoltage guard before buck converter; provides ACOK signal to system controller indicating clean input before enabling downstream regulators. Use Value: Enables reliable "power-good" sequencing with 15ms debounce and eliminates need for separate supervisor IC or discrete clamp circuits. |
| Mobile Internet Device Adapter Interface | USB-PD Sink Input Stage |
|
Use Scenario: Shields LTE modem and baseband processor from overvoltage events caused by non-compliant automotive chargers or damaged cables. IC Role / Device Role / Timing Role: Input-stage protector with 80V surge immunity; ACOK output synchronizes with host firmware power initialization sequence. Use Value: Guarantees system-level ESD robustness (±8kV contact, ±15kV air-gap on IN) while maintaining <1.3mm profile for thin form factors. |
Use Scenario: Safeguards USB-PD sink controller and Type-C port logic from misconfigured source negotiation or cable fault-induced overvoltage. IC Role / Device Role / Timing Role: Overvoltage cutoff element upstream of PD controller; responds to >15.5V input within 2µs and asserts ACOK only after stable 5–15V window detection. Use Value: Supports USB-PD 3.0 compliance by providing deterministic fault isolation without compromising negotiation timing or CC line integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar overvoltage protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14654EWC+T | Fixed 6.8V ±2.9% OVLO threshold; identical WLP package and pinout. | Targeted at 5V/6V systems (e.g., USB 2.0 peripherals), not 12V/15V rails. | Select when protecting lower-voltage subsystems where 15.5V trip would allow damaging overvoltage exposure. |
| TPD3S014RTER | Lower 3.6V OVLO, integrated USB data-line ESD protection, 120mΩ RON. | Optimized for USB 2.0 data + power protection; lacks ACOK flag and soft-start. | Choose only for cost-sensitive USB peripheral designs requiring combined data/power protection-not for high-current PMIC input guarding. |
Compared with MAX14653EWC+T, MAX14654EWC+T offers lower trip voltage for 5V-centric architectures but shares identical thermal, timing, and packaging behavior; TPD3S014RTER trades off current capability and control features for integrated USB data-line protection, making it unsuitable as a direct replacement in high-power mobile power-path roles.

FAQ
What is the exact overvoltage lockout (OVLO) threshold for MAX14653EWC+T?
The MAX14653EWC+T has a factory-trimmed internal OVLO threshold of 15.5V ±3.3%, verified across -40°C to +85°C. This value is fixed and does not require external resistors-OVLO pin is connected to GND to enable the internal setting. The threshold remains stable with temperature, exhibiting <±6% variation over full operating range per characterization data.
Does MAX14653EWC+T support adjustable OVLO, and how is it configured?
Yes, MAX14653EWC+T supports adjustable OVLO via an external resistor divider on the OVLO pin. When OVLO voltage exceeds 0.3V (VOVLO_SELECT), the device switches from internal to external threshold mode. Using R1 = 1MΩ and the formula R2 = R1 × (VIN_OVLO / VOVLO_TH − 1), users can set thresholds from 4V to 20V while retaining all other timing and protection features of the MAX14653EWC+T.
What is the maximum continuous current rating for MAX14653EWC+T, and what limits it?
The MAX14653EWC+T supports 4.5A continuous current, limited primarily by thermal dissipation in its 12-bump WLP package. At +70°C ambient, its power dissipation limit is 1096mW, derating by 13.7mW/°C above that temperature. With 38mΩ RON, 4.5A yields ~770mW conduction loss-well within safe operating area when PCB copper area and airflow meet JEDEC JESD51-7 four-layer board guidelines.
How does the ACOK output function in MAX14653EWC+T, and what external components are needed?
The ACOK output of MAX14653EWC+T is an open-drain flag that pulls low only after VIN stabilizes between 2.5V and the 15.5V OVLO threshold, following 15ms debounce and 30ms soft-start. A pullup resistor (typically 10kΩ to host I/O voltage) is mandatory. ACOK goes high-impedance during thermal shutdown or OVLO fault, enabling direct interface with application processor GPIOs for power-state monitoring.
What surge and ESD protection levels does MAX14653EWC+T provide on the IN pin?
MAX14653EWC+T withstands +80V transient surges on the IN pin with 2Ω series resistance (per Note 1), and delivers ±8kV contact discharge and ±15kV air-gap ESD immunity per IEC 61000-4-2. These ratings are validated on the IN pin only; other pins meet ±2kV HBM. No external TVS diode is required for basic surge suppression, reducing BOM count and board area in mobile designs.
