Overview of TPS2069DDBVR
The Texas Instruments TPS2069DDBVR is a single-channel, current-limited USB power distribution switch designed for applications where precision current limiting is required. This device allows peripheral devices to safely draw power from a host system without the risk of damaging sensitive components due to overcurrent conditions.
Technical Features
The TPS2069DDBVR provides up to 1.5A continuous load current over an input voltage range of 1.8V to 5.5V, making it suitable for various low-voltage applications including USB-powered devices. It features accurate and adjustable current-limiting capability which can be set via an external resistor, offering greater flexibility in controlling the maximum output current.
This device also includes thermal shutdown protection that safeguards the system by turning off the switch when temperatures exceed safe operating limits - this feature automatically resets once normal conditions are restored.
Application Scenarios
The characteristics and capabilities of the TPS2069DDBVR make it highly versatile across numerous application scenarios:
USB Hosts or Hubs: These often require precise control over supplied power to connected peripherals, ensuring they operate within their specified power limits while preventing potential damage from excessive currents.
Battery-Charging Applications: The adjustable and accurate current limit makes this device ideal for battery-charging systems where maintaining specific charging rates is crucial for efficient operation and longevity of batteries.
TPS2069DDBVR Same series model
The TPS2069DDBVR is part of Texas Instruments' TPS20xx series of power distribution switches. Here are some other models within the same series:
TPS2051BD: This model provides similar functionality to the TPS2069DDBVR, but with a slightly lower continuous output current of up to 1A.
TPS2044BD: The TPS2044BD offers four independent switches for applications that require more channels, each capable of delivering an output current up to 500mA.
TPS2065DGNR: With a single-channel configuration like the TPS2069DDBVR, this variant has an even higher continuous load current capability at 2A.
TPS2024IDR: This version features two independently controlled switches and can handle a continuous load current up to 1A per channel.
TPS2069DDBVR Replacement Model
When considering replacements for the TPS2069DDBVR from Texas Instruments, it's crucial to find devices that offer similar functionality and specifications. Here are a few potential alternatives:
TPS2051BD: Also from Texas Instruments, this power-distribution switch offers single-channel current limiting and thermal shutdown features like the TPS2069DDBVR. However, it supports a slightly lower continuous output current of up to 1A.
AP2553W6-7: Diodes Incorporated's AP2553W6-7 provides similar features as the TPS2069DDBVR with adjustable current limit settings but has an additional under-voltage lockout feature which can be beneficial in battery-powered applications.
FPF2143: Fairchild (now ON Semiconductor) offers this full-function load switch that provides over-current protection similar to the TPS2069DDBVR but includes over-voltage and reverse-current blocking capabilities as well.
MIC2025-2YM TR: From Microchip Technology, this device is another single-channel power distribution switch with built-in short-circuit protection comparable to what is found in the TPS2069DDBVR model.
