PT5119 5+1CH DSC Motor Driver FEATURES • • • • • • • • • • An ultra-fine CMOS process has been adopted for low power consumption in a design with no charge-pump. A small 24-pin QFN package (4*4mm) has been adopted. All bridges can be driven simultaneously. Constant-Voltage control H-bridges Drive; Accuracy±5%(at CV DAC=4.0V) Constant-Current H-bridges Drive; Accuracy±5%(at CC DAC=200mV) A constant voltage value and a constant current value are set as arbitrary values by serial setup (4-bit). External resistance is unnecessary in order to change by Built-in DAC. Built-in thermal shutdown circuit.(shut: 150℃/return: 120℃/Hysteresis: 30℃) Built-in UVLO shutdown circuit.(shut: 1.8V/return: 2.0V/Hysterisis: 0.2V) H-Bridge Drive Type/ON Resistance - CH1~3: CV/FS Ron=1.45Ω(TYP) at VM=5V, I=100mA (600mA MAX) - CH4: CV/FS Ron=1.45Ω(TYP) at VM=5V, I=100mA (600mA MAX) - CH5: CC/FS Ron=1.45Ω(TYP) at VM=5V, I=100mA (600mA MAX) • DAC - 4-bit composition - 1~4CH Constant-Voltage: 1.8~4.8V, 0.2V/bit - 5CH Constant-Current: 150~300mV, 10mV/bit • Recommend Operating Condition - Power-supply voltage range: VCC: 2.7~3.6V, VM: 2.7~ 5.5V - Rated power-supply voltage: VCC: 3.3V, VM: 5.0V APPLICATION • DSC BLOCK DIAGRAM Notes: 1.
