A device is disabled in thermal shutdown until the excessive current load is removed, the appropriate enable pins are toggled, or the die temperature cools to 120°C. The undervoltage lockout feature disables the output switches until a valid input voltage, VIN = 2.4V, is present. Once a valid input voltage is present and the SP2026 is enabled, a 1ms soft start prevents momentary voltage drops caused by charging a capacitive load. The SP2026 has a low on resistance, 100mΩ, and supplies a 500mA minimum output current per switch. In overcurrent and thermal shutdown, error flags may be asserted for overtemperature.

Features of the SP2026 device include current limiting, a +2.4V undervoltage lockout, overtemperature shutdown, error flag output, soft start, a switch-on resistance of 100mΩ and a supply current of 100µA. The SP2026-1 device has an active-high enable. The SP2026-2 device has an active-low enable. Input and Output The independent solid state MOSFET switches connect the USB +5.0V supply voltage at the IN pin to the OUTA and OUTB pins when enabled by logic signals at ENA and ENB. The IN pin is the power supply connection to the device and the drain of the output MOSFET switches. THEORY OF OPERATION The SP2026 is a dual integrated high-side power switch optimized for self-powered and buspowered Universal Serial Bus (USB) applications. There are operational conditions that will enable or disable one or more of the output MOSFET switches, depending on the type of hazard. Certain conditions will activate the open-drain error flag transistors forcing the flag outputs to ground. The SP2026 provides the following functions: Typically, the current will flow through the switches from IN to OUTA and OUTB towards the load. If VOUT is greater than VIN when a switch is enabled, the current will flow from OUTA or OUTB to the IN pin because the MOSFET channels are bidirectional when switched on. Under normal operating condition, the MOSFET switches will present 100mΩ resistance when closed. The output MOSFETs and driver circuitry are designed to allow the MOSFET source to be externally forced to a higher voltage than the drain when the switch is off. 1) Independent Solid State Switches: Independent MOSFET switches connect the IN pin to the OUTA and OUTB pins when enabled by logic signals at the ENA and ENB control pins. Fault Flag Conditions Fault conditions disable one or both MOSFET switches, depending on the type of fault. FLGA and FLGB are N-channel, open-drain MOSFET outputs. The active low fault flag occurs when one of the following conditions exist: 2) Fault Flag Conditions: Both the FLGA and FLGB pins are N-channel, open-drain MOSFET outputs capable of sinking a 10mA load to typically 100mV above ground. 3) Undervoltage Lockout: The lockout mechanism monitors the input voltage and will enable the MOSFET switches only when the voltage at the VIN pin is greater than +2.4V. 1. Overcurrent 2. Overtemperature Undervoltage Lockout This voltage lockout mechanism prevents the MOSFET switches from turning on until VIN is greater than +2.4V. 4) Current Limiting Threshold: A current limiting threshold prevents damage to the device and external load. 5) Thermal Shutdown: The SP2026 has dual sensors to detect overtemperature. If the die temperature reaches 140°C and channel A is in current limit, output switch A is disabled and flag A is asserted. Unless channel B current limits, switch B remains enabled and flag B is not asserted. If the die temperature reaches 140°C and channel B is in current limit, output switch B is disabled and flag B is asserted. Unless channel A current limits, switch A remains enabled and flag A is not asserted. If the die exceeds 160°C, both output switches are disabled and both flags are asserted. A device is Rev. 1/23/02 After the switch turns on, if the voltage at VIN drops below +2.15V, the lockout circuitry shuts off both switches. This detection functions only when at least one MOSFET switch is enabled. Output Current Limiting The SP2026 has a preset current-limit threshold. These switch control circuits will implement current limiting which prevents damage to the SP2026 and the external load while allowing a minimum current of 0.5A to be delivered to the load.

A device is disabled in thermal shutdown until the excessive current load is removed, the appropriate enable pins are toggled, or the temperature cools to 120°C. If the SP2026 MOSFET switch is enabled into a heavy load or short-circuit, the switch will immediately go into a constant-current mode, reducing the output voltage. The respective fault flag will pull low until the condition is removed. The delay between a current limit fault and thermal shutdown will vary with ambient temperature, board layout, and load impedance, but is typically several hundred milliseconds. A designer can command a USB controller to recognize the fault and disable the appropriate channel within this time. PRELIMINARY I N F O R M A T I O N The SP2026 MOSFET switches will exhibit very low resistance (100mΩ) or voltage drop until the current limit is reached. The fold back current is the current that is delivered into a short circuit at the output. When a heavy load is connected to the SP2026 switch output, a large transient current may flow until the current limiting circuitry responds. TYPICAL APPLICATIONS The SP2026 will provide a low resistance switch (100mΩ) between the input and output pins. This low resistance will be maintained with increasing current until the 1.25A limit is reached. If load current exceeds this limit, the switches will increase their resistance. The foldback current (500mA minimum) is reached when there is a short applied to either output. The 100mΩ switch resistance is guaranteed for all load currents, increasing or decreasing, that are below 500mA. Bypass Capacitors A 0.1µF to 1.0µF bypass capacitor from the IN pin to the GND pin is recommended to control power supply transients. Refer to Figure 4. Without a bypass capacitor, an output short may cause sufficient ringing and damage the device. Without a bypass capacitor, excessive supply lead inductance is also a concern. Input or output transients must not exceed the absolute maximum supply voltage of VIN(MAX) = +6.0V even for a short duration to avoid risk of damage to the device. Thermal Shutdown Under nominal load conditions, the switch resistances are very low and internal power dissipation is low. Under short circuit conditions, current is limited and internal power dissipation is higher but not extreme. Under intermediate load conditions, both the voltage across the switch and the current through the switch are at intermediate values and internal power dissipation is highest. In this last condition, the die temperature will reach the thermal limit and the switches in both channels will be shut off. As the die subsequently cools, the switch will turn on again. If the load is not removed, the device will thermal cycle in this manner to protect itself from damage. Soft Start Condition The soft start feature of the SP2026 is implemented by holding the output turn-on rise time to 1ms. When off, the device has high impedance MOSFET channels that slowly become low impedance as the device powers on. This prevents an inrush current from causing voltage drops that result from charging a capacitive load and can pull the USB voltage bus below specified levels. This satisfies the USB voltage droop requirements for bus-powered applications. Refer to the circuit in Figure 6. The SP2026 can provide inrush current limiting for applications with large load capacitances where CBULK > 10µF. Refer to the circuit in Figure 7 for a configuration that will meet USB transient regulation specifications with large load capacitances. The SP2026 has dual sensors to detect overtemperature. If the die temperature reaches 140°C and channel A is in current limit, output switch A is disabled and flag A is asserted. Unless channel B current limits, switch B remains enabled and flag B is not asserted. If the die temperature reaches 140°C and channel B is in current limit, output switch B is disabled and flag B is asserted. Unless channel A current limits, switch A remains enabled and flag A is not asserted. If the die exceeds 160°C, both Rev. 1/23/02 Enable Input The ENA and ENB control pins must be driven to a logic high or logic low for a clearly defined signal input. Floating these control lines may cause unpredictable operation.

A USB port provides a +5.0V bus and ground return line in addition to a twisted pair for data. 6) An Undervoltage Lockout ensures that the device remains off unless there is a valid input supply voltage present; 7) +2.7V and +5.0V logic compatible enable inputs; The SP2026 will comply with the following USB requirements: 8) Thermal Shutdown prevents the possibility of catastrophic switch failure from high-current loads; 1) The fault current is well below the UL 25VA safety requirements; 8) The device is available in both active-high and active-low versions. 2) The Flag Outputs are available to indicate fault conditions to USB controllers; Refer to Figures 7 to 14 for typical performance characteristics of the SP2026. 3) The MOSFET switches' low on-resistance meets USB voltage drop requirements; 4) Each MOSFET switch channel can supply 500mA as required by USB downstream devices; VIN ® 5) Soft start eliminates any momentary voltage drops on the upstream port that may occur when the switches are enabled in bus-powered applications.
