TS13001 Galvanic Isolated Blocking 56V Power Load Switch TRIUNE PRODUCTS Features Description • The TS13001 is a galvanic isolated 56V power switch device with bi-directional blocking. The device includes a single integrated 110mOhm high voltage FET allowing high efficiency switching of power loads or other high current applications. The input pin, CLK, controls the turn on/off of the switch. • • • • Low Quiescent Operating Currents Œ 2uA in OFF state Œ 15uA in ON state Œ +/- 2KV galvanic isolation from primary to secondary sides of the device Single control signal for on/off input (CLK) Œ Operation from 2.9V to 5.5V compatible with standard microcontrollers Switch Characteristics Œ High voltage switch with bi-directional blocking in OFF state Œ Single switch device 56V switch and 110mohm Rdson Over current shutoff Œ 5.5Amp typical, 6.6Amp maximum, 4.4Amp minimum -10C to 65C The TS13001 includes several protection features. Each FET has an integrated over-current shut-down to prevent device damage during short-circuit or other unusually high load conditions. If an over-current event is detected for a time the FET is latched off until the CLK pin is held off and turned on again. While the CLK pin is active after an over-current event or in the event of an incorrect turn-on sequence, the DATA pin is toggled at ¼ the CLK frequency.

These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to SRC terminal. (3) ESD testing is performed according to the respective JESD22 JEDEC standard.
