Smart High-Side Power Switch BTS5016-1EKB
1 Overview
Application
• Suitable for resistive, inductive and capacitive loads
• Replaces electromechanical relays, fuses and discrete circuits
• Most suitable for loads with high inrush current, such as lamps
Basic Features
• One channel device
• Very low stand-by current
• 3.3 V and 5 V compatible logic inputs
• Electrostatic discharge protection (ESD)
• Optimized electromagnetic compatibility
• Logic ground independent from load ground
• Very low power DMOS leakage current in OFF state
• Green product (RoHS compliant)
• AEC qualified
Description
The BTS5016-1EKB is a 16 mΩ 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 H4, as well as LEDs in the harsh
automotive environment.
