PT5116 5+1CH Motor Driver FEATURES • • • • • • • • • • An ultra-fine CMOS process has been adopted for low power consumption in a design with no charge-pump. A small 28-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℃/Hysterisis: 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=1.3Ω(TYP) at VM=5V, I=100mA (600mA MAX) - CH4: CC/CV/FS Ron=1.3Ω(TYP) at VM=5V, I=100mA (600mA MAX) - CH5: CC/FS Ron=1.3Ω(TYP) at VM=5V, I=100mA (600mA MAX) • PI Drive Type/ON Voltage - 1~2CH: Nch open drain Von=0.5V(MAX) at I=30mA • DAC - 4-bit composition - 1~4CH Constant-Voltage: 1.8~4.8V, 0.2V/bit - 4~5CH Constant-Current: 150~300mV, 10mV/bit • Recommend Operating Condition - Power-supply voltage range: VCC: 2.5~5.5V, VM: 1.9~ 5.5V - Rated power-supply voltage: VCC: 3.3V, VM: 5.0V BLOCK DIAGRAM Notes: 1.
