TPS2559QWDRCTQ1

Power Distribution Switches, Load Drivers Overview

The TPS2559QWDRCTQ1 is an automotive-grade power distribution switch featuring a single N-channel output. It supports load voltages from 2.5 V to 6.5 V and delivers up to 5.5 A continuous current. The device includes an adjustable current limit ranging from 1.2 A to 4.7 A, set via external resistors. Key electrical parameters include a maximum on-resistance of 16 mOhms, a maximum turn-on time of 15 ms, and a maximum fall time of 8 ms. It operates within a temperature range of -40°C to +125°C and is housed in a 10-VSON package.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'CTQ1' confirms the tape-and-reel packaging format and automotive qualification status. Ensure the design utilizes the correct resistor values to achieve the required 1.2 A to 4.7 A adjustable current limit threshold. Confirm compatibility with the 10-VSON thermal pad requirements for adequate heat dissipation at maximum load conditions.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when adjustable current limiting is required rather than fixed thresholds. It is suitable for applications needing high efficiency due to low on-resistance. Consider the 10-VSON package size constraints and the need for external programming resistors for current setting compared to fixed-limit alternatives.
