Product details
Overview
MP3416GJ-Z from Monolithic Power Systems is a low-quiescent-current (9.5 µA), 1.1 A peak switching current, synchronous step-up DC-DC converter with true output disconnect, adjustable low-battery detection (LBI/LBO), and down-mode operation when VIN > VOUT. It operates from 0.86 V input to deliver regulated 1.8–5.5 V output, enabling single-cell Li-ion, NiMH, or alkaline battery-powered systems requiring high light-load efficiency and battery state monitoring.
For engineers reviewing the MP3416GJ-Z datasheet, MP3416GJ-Z pinout, MP3416GJ-Z application, or MP3416GJ-Z equivalent, this device is selected for ultra-low-power boost conversion in space-constrained, battery-sensitive designs where shutdown current (<650 nA), output isolation, and integrated battery voltage monitoring are critical design requirements.
Technical Context
The MP3416GJ-Z employs peak-current-mode control with variable-frequency boundary conduction mode (BCM) to achieve fast transient response and stable regulation across wide input/output ratios. Its internal P-channel synchronous rectifier eliminates external Schottky diode losses, while the dedicated DIS-FET enables true output disconnect during shutdown and down-mode operation.
It integrates a precision 504 mV feedback reference, programmable low-battery detection threshold (0.4 V on LBI with 70 mV hysteresis), and thermal shutdown at 155°C with 20°C hysteresis. The EN pin supports logic-level enable/disable with <100 nA leakage, and the FB node accepts standard resistor-divider networks for output voltage setting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Quiescent Current | 9.5 µA - Enables multi-year battery life in always-on sensor nodes and remote controls. |
| Shutdown Current | <650 nA - Prevents battery drain during storage or standby in portable medical devices. |
| Switching Current Limit | 1.1 A (typ.) - Supports up to ~100 mA output at 3.3 V from 1.25 V input, sufficient for display backlight or RF transceiver bias. |
| Feedback Reference Voltage | 504 mV (±2 mV) - Enables accurate, stable output voltage setting via external resistor divider (e.g., 100 kΩ/178 kΩ for 3.3 V). |
| Low-Battery Threshold | 0.4 V on LBI pin - Allows precise battery voltage monitoring with external resistor divider; LBO provides open-drain flag for system MCU. |
| Output Disconnect | True - Internal DIS-FET isolates VOUT from VIN in shutdown, eliminating reverse leakage paths in battery-powered systems. |
| Start-Up Voltage | 1.25 V - Permits reliable startup from partially discharged single-cell alkaline or NiMH batteries. |
Pinout & Package
MP3416GJ-Z is housed in an 8-pin TSOT23 package (2.9 mm × 1.6 mm × 0.85 mm), optimized for ultra-compact PCB layouts in handheld and wearable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (FB) | Feedback Input | Connects to resistor divider tap; senses output voltage and closes regulation loop via internal 504 mV error amplifier reference. |
| 2 (GND) | Power Ground | Primary return path for SW, OUT, IN, and internal control circuitry; must be low-impedance and tied directly to power plane. |
| 3 (SW) | Switch Node | Drives external inductor; carries high di/dt switching current; requires short, wide trace to minimize EMI and voltage spikes. |
| 4 (OUT) | Synchronous Rectifier Source | Output of internal P-MOSFET; connects to output capacitor; supplies regulated VOUT with no external diode needed. |
| 5 (IN) | Input Supply | Accepts 0.86–5.5 V input; requires local 10 µF ceramic bypass capacitor placed adjacent to pin. |
| 6 (EN) | Enable Control | Logic-compatible input (VIH > 0.7 V, VIL < 0.2 V); asserts full regulation or forces complete shutdown with output disconnect. |
| 7 (LBI) | Low-Battery Input | Analog input for resistor-divider-scaled battery voltage; triggers LBO when voltage falls below 0.4 V (70 mV hysteresis). |
| 8 (LBO) | Low-Battery Output | Open-drain flag output; pulled low by IC when LBI < 0.4 V; requires external pull-up to indicate battery depletion to host MCU. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Quiescent Current | 9.5 µA enables >5-year battery life in 10 µA average-load IoT sensors using two AA cells. |
| True Output Disconnect | Internal DIS-FET breaks VIN–VOUT path in shutdown, reducing system standby current to sub-µA levels. |
| Adjustable Low-Battery Detection | LBI/LBO interface allows user-defined battery cutoff (e.g., 0.9 V cell voltage) without external comparators or ADC resources. |
| Synchronous Rectification | Integrated P-MOSFET replaces lossy Schottky diode, improving light-load efficiency to 80% at 100–200 µA output. |
| Down-Mode Operation | Automatically transitions to pass-through mode when VIN exceeds VOUT − 0.2 V, minimizing dropout and power loss. |

FAQ
What is the minimum input voltage required for MP3416GJ-Z to start switching?
The MP3416GJ-Z requires a minimum start-up voltage of 1.25 V at the IN pin to initiate regulation. Below this threshold, the device remains in UVLO and will not switch-even if the EN pin is asserted high. Once started, it continues operating down to 0.86 V input, supporting deep battery discharge in single-cell systems.
Does MP3416GJ-Z require an external Schottky diode?
No. The MP3416GJ-Z integrates a synchronous P-channel MOSFET as the rectifier, eliminating the need for an external Schottky diode. This reduces component count, improves light-load efficiency (up to 80% at 100–200 µA), and lowers thermal stress compared to diode-based boost converters.
How is the low-battery detection threshold set on MP3416GJ-Z?
The LBI pin has a fixed 0.4 V internal threshold with 70 mV hysteresis. To detect a specific battery voltage (e.g., 1.2 V), connect LBI to VIN through a resistor divider such that the divided voltage equals 0.4 V at the target battery level. For example, use R1 = 1 MΩ and R2 = 333 kΩ to trigger at 1.2 V.
What happens to the output during shutdown when EN is pulled low?
When EN is driven below 0.2 V, the MP3416GJ-Z halts all switching, disables internal control circuits, and turns off the internal DIS-FET. This physically disconnects the OUT pin from the IN pin, limiting output leakage to <0.65 µA and preventing battery discharge through the load or output capacitor.
Can MP3416GJ-Z operate when input voltage exceeds the output voltage?
Yes. When VIN rises above VOUT − 0.2 V, the MP3416GJ-Z automatically enters down-mode operation: the internal DIS-FET modulates conduction to pass input voltage to output with minimal dropout, avoiding inefficient boosting and reducing power loss and heat generation.
What is the recommended inductor value for MP3416GJ-Z in a 3.3 V output application?
MPS recommends a 1.5 µH to 3.3 µH shielded chip inductor rated for ≥1.1 A saturation current. A 3.3 µH inductor (e.g., Coilcraft XAL5030-332MEB) balances switching frequency (~1–2 MHz), output ripple, and efficiency for typical 10–100 mA loads at 3.3 V output.
Is MP3416GJ-Z RoHS and REACH compliant?
Yes. MP3416GJ-Z is lead-free, halogen-free, and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation, including material declarations and test reports, is available from Monolithic Power Systems upon request.
