Smart High-Side Power Switch

Infineon Technologies 

Open-load detection, OUT1 or OUT2

OFF-state diagnostic condition:

Open load, if VOUT > 2.7 V typ. (IN low)

IL(OL) typ. 2µA

An external resitor can be used to increase the open

load detection current

For inductive load currents up to the limits defined by ZL

(max. ratings and diagram on page 12) each switch is

protected against loss of Vbb.

Consider at your PCB layout that in the case of Vbb dis-

connection with energized inductive load all the load current

flows through the GND connection.
