The ITS42k5D-LD-F demo board is fully equipped with external components as well as the device. This demo board user’s guide contains all necessary information for using of the this board to evaluate the ITS42k5D-LD-F. Table 1 Device Overview Type Number of Output Channels current ITS42k5D-LD-F Dual channel device 1.1 Protection Features Package Ordering Information PG-TSON-10 Device OPN: 250 mA per Short-circuit, DEMOBOARDITS42k5DTOBO1 channel Overtemperature Name: DEMOBOARD ITS42k5D UndervoltageSP No.: SP001213116 Lockout, Open Load Detection General Description The ITS42k5D-LD-F is a dual channel high-side PMOS power switch. The device is equipped with integrated protection and diagnostic features. The diagnosis can be read out from two separate open drain outputs in order to indicate overload, short circuit, open load and overtemperature conditions. The device controls the respective channel one or two by the two separate input pins i.e. IN1 and IN2. When both inputs are low the device is in OFF condition. Each channel of the device is able to drive loads up to 250mA. The ITS42k5D-LD-F is capable of switching resistive, capacitive and inductive loads (e.g. sensor units, LEDs, relays, valves) in harsh industrial environments. An integrated freewheeling diode per channel enables driving of inductive loads as well as long wire lengths.
