The design is based on Infineons Smart Power Technology SPT which allows bipolar, CMOS and power D-MOS devices on the same monolithic circuit. Operation modes forward (cw), reverse (ccw) and brake are invoked by two control pins PWM and DIR. Protection and a reliable diagnosis of overcurrent, openload, short-circuit to ground, to the supply voltage or across the load are integrated. Detailed diagnostic Data Sheet, Rev.3.2 1 2010-09-10TLE 6209 R information is given via the 8 bit SPI status word. An integrated chopper current limitation limits the current e.g. to reduce power dissipation during mechanical block of a DC motor. Several device parameters can be set by the SPI control word. A three-level temperature monitoring with prewarning, warning and shutdown is included for controlled operation under critical power loss conditions. The full protection and diagnosis capability make the device suitable especially for safety relevant applications, e.g. in automotive ECUs. 1.2 Pin Configuration (top view) TLE 6209R 1 20 GND GND 19 2 OUT 1 OUT 2 3 18 OUT 1 OUT 2 4 17 V V S S 5 16 DRV SCLK 6 15 SDI V CC 7 14 PWM SDO 8 13 DIR CSN 9 12 INH DIS 10 11 GND GND Metal slug, connected to GND Pin Definitions and Functions V Power Supply Voltage V 5 V Logic Supply S CC DRV Input for Charge pump buffer GND Ground capacitor SDI Serial Data Input SDO Serial Data Output SCLK Serial Clock Input CSN Chip-Select-Not Input OUT Power Output PWM PWM Input DIR Direction Input DIS Disable Input INH Inhibit Data Sheet, Version 3.2 2 2010-09-10
