Notes
1. Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
2. Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not
designed for continuous repetitive operation.

Notes
1. Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
2. Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not
designed for continuous repetitive operation.

Description
The BTT6020-1EKA is a 20 m
Ω single channel Smart High-Side Power Switch, embedded in a PG-DSO-14-47
EP, Exposed Pad package, providing protective functions and diagnosis. The power transistor is built by an
N-channel vertical power MOSFET with charge pump. The device is integrated in Smart6 technology. It is specially
designed to drive lamps up to 5 x P21W 24V or 1 x 70W 24V, as well as LEDs in the harsh automotive
environment.

Notes
1. Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
2. Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not
designed for continuous repetitive operation.
