Currents are positive into, negative out of the specificed terminal.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionSiP43101 is a dual power switch IC which contains all control and power switching circuitry required to drive resistive and inductive loads in industrial applications. The output switches are NPN power transistors which can be configured as either high-side or low-side switches. These switches can operate from voltages as high as 35 V and have a continuous output current rating of 200 mA, combined or individually. Internal zener diodes are provided to clamp the power switch voltages to safe levels when driving inductive loads. The IN1 pin is a non-inverting input which controls the output of switch 1. A 2-input Exclusive OR gate input controls switch 2, allowing switch 2 to be controlled by either an inverting or non-inverting control signal. SiP43101 contains under voltage lockout, UVLO, a user definable turn on delay, current limit, short circuit protection, and thermal shutdown.
SiP43101 is available in 16-pin TSSOP and PowerPAK MLP-44 packages for operation over the temperature range of −40 to 85 .
