TPS2557 Acorn - Current Adjustable Load Driver
Availability: Depending on availability, this product might take longer than usual to ship. (Up to three weeks).
Easily turn your project into a lower power system with the TPS2557 power switch and load driver from Texas Instruments, delivered on an easy to use breakout.
This acorn is similar to our popular TPS22917 Acorn, but with expanded capabilities in terms of interface and additional features not available on the TPS22917.
The TPS2557 Acorn allows for fault detection, as well as providing the user the opportunity to set the current limiting resistor. For this chip, there must be a current limiting resistor soldered on before use.
Please reference the technical documentation and TPS2557 data sheet for more information on determining the current limiting resistor.
BULK ORDERS: All bulk orders (quantities of 10 or more) have 3 week lead times at the moment. You can expect lead times to improve after January 2021.
