Product details
Overview
TCK206G,LF from Toshiba Electronic Devices & Storage Corporation is a 0.75 V ultra-low-voltage load switch IC with reverse current blocking, 18.4 mΩ typical ON resistance at 0.75 V/−1.5 A, 2.0 A DC output capability, and slew rate control-designed for power management in space-constrained portable electronics such as smartphones.
For engineers reviewing the TCK206G,LF datasheet, TCK206G,LF pinout, TCK206G,LF application, or TCK206G,LF equivalent, key selection considerations include its active-high control with internal pull-down, absence of auto-discharge function, ultra-small WCSP4C package (0.9 mm × 0.9 mm), and guaranteed operation down to 0.75 V input.
Technical Context
The TCK206G,LF integrates a single N-channel MOSFET pass switch with built-in reverse current blocking activated during OFF state, eliminating external back-to-back FETs. Its slew rate control driver limits inrush current by shaping VOUT rise time to 180 μs (typ.) at VIN = 0.75 V with 500 Ω/0.1 μF load.
Unlike TCK207G and TCK208G, TCK206G,LF lacks output auto-discharge and uses an active-high CONTROL pin with internal pull-down to GND-ensuring default OFF state when un-driven. It supports input voltages from 0.75 V to 3.6 V and operates across −40 °C to +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.75 V to 3.6 V - enables direct integration into sub-1V core rails and multi-rail PMIC outputs. |
| ON Resistance | 18.4 mΩ (typ.) at 0.75 V/−1.5 A - minimizes conduction loss and thermal rise under low-VIN, high-current conditions. |
| Output Current | 2.0 A DC - supports high-current peripherals like camera modules or RF front-ends without external current limiting. |
| VOUT Rise Time | 180 μs (typ.) at VIN = 0.75 V - controlled inrush prevents supply rail collapse during hot-plug events. |
| Reverse Blocking Current | ≤10 μA max at VOUT = 3.6 V/VIN = 0 V - blocks leakage from downstream circuits back into powered-off domains. |
| Quiescent Current | 22 μA (typ.) in ON state - negligible bias consumption for always-on subsystems. |
| Standby Current | 5 μA max in OFF state - preserves battery life in standby modes of portable devices. |
Pinout & Package
Package: WCSP4C (0.9 mm × 0.9 mm, 0.5 mm pitch, 0.5 mm height, 0.9 mg typical weight) - optimized for ultra-dense mobile PCB layouts with minimal board area footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CONTROL (B2) | Active-high logic input with internal ~MΩ pull-down | Drives internal pass FET; defaults to OFF if left floating; compatible with 0.75–3.6 V logic levels. |
| GND (B1) | Power ground reference | Return path for both control circuitry and power switch; must be low-impedance connection to system ground plane. |
| VIN (A2) | Main power input | Accepts 0.75–3.6 V supply; requires ≥1.0 μF ceramic capacitor placed adjacent to minimize input ripple and transient droop. |
| VOUT (A1) | Switched output | Delivers regulated load current up to 2.0 A; reverse current blocking active when CONTROL = LOW. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low 0.75 V minimum input voltage | Enables direct switching of advanced low-power SoC I/O or memory rails without level-shifting or boost conversion. |
| Integrated reverse current blocking | Eliminates need for external back-to-back FETs or diodes, reducing BOM count and layout complexity in battery-isolated domains. |
| Slew rate–controlled turn-on | Prevents large inrush currents that could destabilize shared power rails or trigger overcurrent protection in upstream supplies. |
| Internal pull-down on CONTROL pin | Guarantees safe default-OFF behavior during power-up, reset, or MCU GPIO initialization-no external resistor required. |
| WCSP4C ultra-small package | Reduces occupied PCB area to <1 mm², critical for antenna clearance zones and stacked-die module designs in modern smartphones. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCK207G,LF | Includes output auto-discharge and same WCSP4C package; otherwise identical electrical specs and pinout. | Required where rapid VOUT discharge (<50 μs fall time) is needed after shutdown to meet system-level reset timing. | Select TCK207G,LF only if auto-discharge is mandatory; TCK206G,LF saves cost and avoids unnecessary discharge current in static loads. |
| TPS22916BYFPR | TI part in DSBGA4 (0.9 mm × 0.9 mm); 17 mΩ RON at 1.2 V but minimum VIN = 1.0 V; no reverse blocking. | Lacks reverse current blocking-requires external diode or dual-FET solution for backfeed prevention. | Choose TCK206G,LF over TPS22916BYFPR when reverse blocking is essential and sub-1V operation is required. |
Compared with TCK207G,LF and TPS22916BYFPR, the TCK206G,LF uniquely delivers guaranteed 0.75 V operation with integrated reverse blocking in the same ultra-small WCSP4C footprint-making it optimal for lowest-voltage, highest-density battery-powered systems where auto-discharge is not needed.

FAQ
What is the minimum input voltage supported by the TCK206G,LF?
The TCK206G,LF supports a minimum input voltage of 0.75 V, enabling direct use with emerging ultra-low-voltage rails such as 0.8 V GPU cores or energy-harvesting sources. This specification is guaranteed across the full operating temperature range of −40 °C to +85 °C and is validated per Toshiba's Electrical Characteristics table.
Does the TCK206G,LF provide reverse current blocking, and how is it implemented?
Yes, the TCK206G,LF provides reverse current blocking in the SW OFF state, with maximum leakage of 10 μA at VOUT = 3.6 V and VIN = 0 V. This function is implemented via internal circuitry that disables the body diode path of the integrated N-channel MOSFET, eliminating need for external back-to-back FETs. The feature is active whenever the CONTROL pin is low.
Is the TCK206G,LF pin-compatible with TCK207G,LF or TCK208G,LF?
Yes, the TCK206G,LF shares identical WCSP4C package dimensions, pin assignment, and pinout with TCK207G,LF and TCK208G,LF-including CONTROL (B2), GND (B1), VIN (A2), and VOUT (A1). However, functional differences exist: TCK206G,LF has no auto-discharge and uses active-high control with internal pull-down, unlike TCK207G,LF (auto-discharge, active-high) and TCK208G,LF (auto-discharge, active-low).
What is the typical ON resistance of the TCK206G,LF at 0.75 V input?
The typical ON resistance of the TCK206G,LF is 18.4 mΩ at VIN = 0.75 V and IOUT = −1.5 A, as specified in Toshiba's Electrical Characteristics table. This value is measured under standard test conditions and reflects low conduction loss critical for maintaining voltage regulation in low-VIN, high-current applications.
Does the TCK206G,LF require an external pull-down resistor on the CONTROL pin?
No, the TCK206G,LF includes an internal pull-down resistor (equivalent to several MΩ) between CONTROL and GND, ensuring the device remains in the OFF state when the CONTROL pin is left unconnected or floating. This eliminates the need for an external resistor and simplifies design for systems with limited GPIO drive capability.
