Product details
Overview
LTC4412MPS6#TRMPBF from Analog Devices is a high-reliability PowerPath™ controller IC that manages an external P-channel MOSFET to implement near-ideal diode OR'ing between two DC power sources. It delivers 20mV forward regulation voltage (VFR), supports 2.5V–28V battery and 3V–28V adapter input ranges, and operates across –55°C to 150°C. It enables automatic switchover in battery-backed portable systems such as USB-powered peripherals and industrial handheld computers.
For engineers reviewing the LTC4412MPS6#TRMPBF datasheet, LTC4412MPS6#TRMPBF pinout, LTC4412MPS6#TRMPBF application, or LTC4412MPS6#TRMPBF equivalent, key selection criteria include its ultra-low quiescent current (11µA typ), reverse turn-off threshold (20mV), gate clamp voltage (7V), STAT open-drain sink capability (10µA), and AEC-Q100-qualified extended temperature operation.
Technical Context
The LTC4412MPS6#TRMPBF uses an analog comparator-based control architecture with ±20mV precision thresholds for forward regulation (VFR) and reverse turn-off (VRTO). Its linear gate driver delivers up to 85µA sink current and includes internal voltage clamping (VG(ON) = 7V) to protect the external P-MOSFET gate oxide.
It features dual-supply operation: powered from VIN when only battery is active, and seamlessly transitions to SENSE-derived supply when auxiliary voltage exceeds VIN by ≥20mV. The CTL pin provides logic-level manual override (VIH = 0.635V min), while STAT offers open-drain status signaling with 4.5µs turn-on time and 10µA guaranteed sink current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Regulation Voltage (VFR) | 20mV typical - maintains ultra-low conduction loss across MOSFET, enabling >99.5% efficiency at high load currents. |
| Reverse Turn-Off Threshold (VRTO) | 20mV typical - ensures clean, hysteresis-stabilized disconnection of primary source when auxiliary supply rises. |
| Quiescent Current (IQFL) | 11µA typical at 3.6V - minimizes battery drain during standby, critical for long-life portable applications. |
| Operating Temperature Range | –55°C to +150°C - qualified for harsh-environment automotive and industrial use, exceeding standard commercial grade. |
| GATE Sink Current (IG(SNK)) | 85µA max - drives large P-MOSFETs with low RDS(ON), supporting multi-amp load sharing without external buffers. |
| STAT Sink Current (IS(SNK)) | 10µA min - reliably biases external pull-up resistors to interface with 1.8V–5V microcontrollers or enable auxiliary switches. |
| CTL Input Threshold (VIH) | 0.635V min - compatible with low-voltage logic (e.g., 1.2V/1.8V I/O), enabling direct connection to modern MCUs without level shifting. |
Pinout & Package
Package: 6-lead TSOT-23 (ThinSOT™), 1mm profile, RoHS-compliant, thermal resistance θJA = 230°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Primary power sense & supply input | Connects to battery or main DC source; powers internal circuitry when auxiliary is absent; protected against reverse polarity down to –14V. |
| GND (Pin 2) | Power and signal reference | Common return path for all internal blocks; must be low-impedance to avoid VFR/VRTO threshold errors due to IR drop. |
| CTL (Pin 3) | Digital control enable input | Logic-high (>0.635V) forces GATE to VG(OFF) (~0.25V) and pulls STAT low; internal 3.5µA pull-down ensures fail-safe off-state if floating. |
| STAT (Pin 4) | Open-drain status output | Sinks 10µA when auxiliary supply is active (SENSE > VIN + 20mV); used for MCU interrupt or driving auxiliary P-MOSFET gate via pull-up resistor. |
| GATE (Pin 5) | External P-MOSFET gate driver | Delivers regulated gate voltage to maintain 20mV VDS; clamped to ≤7V below higher of VIN/SENSE to prevent gate overvoltage. |
| SENSE (Pin 6) | Auxiliary power sense & supply input | Connects to wall adapter or backup source; powers IC during switchover; protected against negative transients to –14V. |
Key Features
| Feature | Design Value |
|---|---|
| Low-loss PowerPath™ control | Replaces Schottky diodes with <20mV drop, reducing heat dissipation by >95% versus 0.3V diode in 1A applications. |
| Wide input voltage range | 2.5V–28V on both VIN and SENSE pins supports single-cell Li-ion to six-series battery packs and universal AC adapters. |
| Reverse battery protection | VIN and SENSE tolerate –14V, eliminating need for external reverse-polarity protection diodes in battery-input paths. |
| MOSFET gate voltage clamp | 7V clamp (VG(ON)) prevents gate oxide stress on logic-level P-MOSFETs, enabling robust design without external Zener protection. |
| Automotive-grade qualification | AEC-Q100 Grade 1 (–40°C to +125°C ambient) and extended MP grade (–55°C to +150°C junction) ensure reliability in under-hood and industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power-path control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC4413EDHC#PBF | Dual-channel version in 16-lead DFN; supports independent control of two power paths; higher IQ (25µA); no extended temp grade. | Required for dual-input redundancy (e.g., dual battery + adapter) where channel isolation is mandatory. | Select when simultaneous management of two independent OR'ing paths is needed; not a drop-in replacement due to pin count and package mismatch. |
| TPS2113APWR | Single-channel auto-switching IC in 8-pin TSSOP; fixed 115mV forward drop; no CTL/STAT pins; rated –40°C to 85°C only. | Suitable for cost-sensitive consumer electronics where ultra-low loss and extended temperature are not required. | Choose for simplified BOM in commercial-grade applications; lacks gate clamp, reverse protection, and STAT signaling of LTC4412MPS6#TRMPBF. |
Compared with LTC4412MPS6#TRMPBF, LTC4413EDHC#PBF adds dual-path flexibility at the cost of higher quiescent current and no extended temperature support, while TPS2113APWR trades precision regulation and ruggedness for lower unit cost and smaller feature set - making LTC4412MPS6#TRMPBF optimal for high-reliability, low-loss, wide-temperature designs.

FAQ
What is the maximum junction temperature specification for LTC4412MPS6#TRMPBF?
The LTC4412MPS6#TRMPBF is tested and guaranteed over a junction temperature range of –55°C to +150°C. This MP-grade qualification meets AEC-Q100 requirements for automotive under-hood applications and supports industrial deployments in thermally aggressive environments. Thermal design must account for θJA = 230°C/W in the TSOT-23 package; derating is recommended above 125°C to ensure long-term reliability.
How does the LTC4412MPS6#TRMPBF achieve 20mV forward regulation voltage?
The LTC4412MPS6#TRMPBF achieves 20mV forward regulation (VFR) through a precision analog comparator that continuously monitors the voltage difference between VIN and SENSE pins. When only VIN is active, the internal gate driver adjusts the GATE pin voltage to maintain exactly 20mV across the external P-MOSFET's drain-source terminals - effectively regulating VDS as a controlled linear element rather than relying on fixed RDS(ON).
Can the STAT pin of LTC4412MPS6#TRMPBF drive a logic-level input directly?
Yes, the STAT pin of LTC4412MPS6#TRMPBF is an open-drain output capable of sinking 10µA minimum, making it compatible with standard CMOS logic inputs (e.g., 3.3V or 5V microcontrollers) when used with an appropriate pull-up resistor (e.g., 10kΩ to 3.3V yields 0.033V drop). Its 4.5µs turn-on time ensures responsive status reporting without timing constraints in most embedded systems.
Does LTC4412MPS6#TRMPBF require external components for basic operation?
Yes, LTC4412MPS6#TRMPBF requires at least one external P-channel MOSFET and bypass capacitors on VIN and SENSE (0.1µF–10µF ceramic). Optional components include a pull-up resistor on STAT for MCU interfacing and a series resistor on CTL for noise immunity. No external feedback network or compensation is needed - the 20mV regulation and 20mV turn-off thresholds are internally fixed and trimmed.
Is the LTC4412MPS6#TRMPBF pin-compatible with other LTC4412 variants like LTC4412ES6#TRMPBF?
Yes, LTC4412MPS6#TRMPBF is pin-compatible with all other S6-package variants (e.g., LTC4412ES6#TRMPBF, LTC4412IS6#TRMPBF, LTC4412HS6#TRMPBF) because they share identical 6-lead TSOT-23 footprint, pinout, and electrical interface. The only differences are temperature grade, test screening, and reliability documentation - allowing direct substitution in existing layouts when upgrading to extended temperature operation.
