Overview
The UC17133J is a high-side smart power switch manufactured by Texas Instruments. It operates within an 8V to 65V supply range and provides a continuous output current of 300mA with a peak capability of 700mA. The device features a fixed 30% input comparator hysteresis and includes integrated overload, short circuit, and power interruption protection. A regulated 6V reference voltage is available for external circuitry.
Feature Summary
- Configured exclusively for high-side switching applications
- Integrated programmable turn-on delay and power interruption protection
- Internal high-current clamps for safe inductive load discharge
- Open-collector LED output for status indication
Applications
- Driving resistive or inductive loads from the high side
- Automotive systems requiring high-side control
- Industrial equipment with inductive load management
Procurement Notes
Verify that the specific part number corresponds to the UCX7133 family variant intended for high-side configurations only. Confirm the package type matches the required pin count and footprint. Ensure the operating temperature range aligns with the application environment. Cross-reference the datasheet revision to confirm feature consistency.
Selection Notes
Select this component when a dedicated high-side driver is required without low-side functionality. The UC17133 differs from the UC17132 by lacking the HS/LS flexibility and programmable hysteresis options. Consider the internal 72V clamp for inductive loads to simplify external circuit design.
Part Context
The UC17133 belongs to the UC1713x family of smart power switches, which also includes the UC17131 (low-side) and UC17132 (universal). These devices are designed to replace discrete transistor solutions by integrating protection logic and drive circuits into a single compact package.

FAQ
Can the UC17133 be used for low-side switching?
No, the UC17133 is configured exclusively for high-side switching applications.
How is the input comparator hysteresis set on the UC17133?
The UC17133 has a fixed 30% input comparator hysteresis and does not offer programmable hysteresis like the UC17132.
