Two half ÿ Supply voltage VDD 4.5V to 5.5V bridge driver outputs can be used to create a full bridge driver. ÿ Supply voltage VDD2 7.5V to 17V The load between the two outputs could be, for example, a DC ÿ Serial μP data interface motor. These 8 single power half bridges can be used to drive ser- ÿ Cascadable vomotors and single ended resistive or inductive loads referenced ÿ Full duplex serial interface: control on input; to ground or battery. All loads can be activated at the same time diagnostic on output with a continuous current load of 250mA each. In case of only two ÿ Short-circuit current protection active half bridges, the continuous current load is increased to ÿ Short-circuit current limited 500mA each. An over temperature protection circuit is integrated ÿ Thermal overload-protection into the IC and deactivates the half bridge outputs (high imped- (switching all outputs to high impedance) ance) in case of thermal overload. In case of over current the low ÿ Under- and over voltage protection and high side driver of each single half bridge are current limited ÿ Reverse battery protection (up to 16 V) and deactivated with a 100ms delay. This information can also be ÿ Output slew rate limited ( < 200 mV/μs) read through the diagnosis pin. ÿ – 40°C to + 125°C operating temperature ÿ SO28 package; QFN package on demand application ÿ DC-Motor driver ÿ Servo motor driver Block diagram V Bat V CP 5V VDD VDD VDD2 Charge Pump POR package Pin Name Description 1 OUT2 Driver-output 2 VSS Supply-ground 3 DATAIN Serial data-input 4 DATAOUT Serial data-out 5 VSS Supply-ground 6 OUT3 Driver-output 7 VDD2 Battery-voltage 8 OUT4 Driver-output 9 VSS Supply-ground 10 VDD Logic-supply-voltage 11 RBIAS Resistor for current reference 12 TEST Test-pin for measuring the temperature protection 13 OUT5 Driver-output 14 VDD2 Battery-voltage 15 OUT6 Driver-outpput 16 VSS Supply-ground 17 STRBIN 18 SRBOUT 19 VSS Supply-ground 20 OUT7 Driver-output 21 VDD2 Battery-voltgae 22 OUT8 Driver-output 23 VSS Supply-ground 24 VCP External capacitor for the charge-pumpe 25 CLK 26 VSS 27 OUT1 Driver-output 28 VDD2 Battery-voltage OUT2 1 28 VDD2 VSS 2 27 OUT1 DATIN 3 26 VSS DATOUT 4 25 CLK VSS 5 24 VCP OUT3 6 23 VSS VDD2 7 22 OUT8 OUT4 8 21 VDD2 VSS 9 20 OUT7 VDD 10 19 VSS RBIAS 11 18 STRBOUT TEST 12 17 STRBIN OUT5 13 16 VSS VDD2 14 15 OUT6 SO28 Activation of IC (High active ), the data are read back at rising edge Cascading-signal (High active) Clock for feeding/selecting of the data, data are latched on at falling edge Supply-ground Driver 8 OUT1 STRIBIN DATIN Serial Interface With Latch DATOUT CLK external µC 16 T= 100ms STRBOUT M OUT4 16 Current Observe OUT5 M M OUT6 OSC TEST OUT2 OUT3 Level Shift 8 Test Mode Driver 1 Temp.
