SHIELD_BTS50025-1TEA This board is intended to provide a simple, easy-to-use user interface for getting familiar with Infineon's High Side Switch BTS50025-1TEA on PC

Overview

The BTS50025-1TEA shield for Arduino comes with four samples of BTS50025-1TEA, to drive four different loads.
BTS50025-1TEA is the lowest ohmic smart high-side power switch in DPAK available in the market; its typical RDS(ON) is 2.5mΩ and it can drive a nominal DC current of up to 24A.
Designed for relay and fuse replacement in power distribution and junction boxes, BTS50025-1TEA can drive resistive, capacitive and inductive loads.
BTS50025-1TEA high current applications (e.g. ECU power feeds, auxiliary power outlets, PTC heaters, rear windows heaters) and applications with high switching cycles and high energy requirements (e.g. starter relay in "start-stop" systems, electric brake vacuum pumps).
The shield can be used in stand-alone mode or controlled either by an Arduino board or the ARM® powered Infineon XMC™ microcontroller kits using the Arduino form factor.

Summary of Features

  • four BTS50025-1TEA
  • Each BTS50025-1TEA can be independently controlled from the Arduino digital connector (D9 to D12)
  • The load current sensed by each BTS50025-1TEA can be sampled by the Arduino on the analog connector (A0 to A3)
  • Test points for each input control, each current sense and each output.

Benefits

  • Easily evaluate the BTS50025-1TEA driving a specific load
  • Check BTS50025-1TEA behavior using PWM signals generated by the Arduino board
  • Capture current profiles of the driven loads on the Arduino
  • Easy plug of scope probes to monitor signals on the board.

Potential Applications

  • Automotive: starter relay in "start-stop" systems, electric brake vacuum pumps, PTC heating systems, glow plugs, rear deicer etc.
  • Robot applications: 12V DC motors drive: up to 4 motors, up to 20A each.
  • 3D printer: heating elements control (heating plate, heating heating resistance), protected 12V supply for control boards
