Thermal Performance Characteristics
Application Circuit
Note 1: Connect the VS2A terminal to the lower supply voltage (5 V).
Note 2: Supply smoothing capacitor* should be connected between each supply terminal (Vcc, VS2A, and VS1A/B)
and GND terminal. *: (Ex.): Capacitors of tens of μF and 0.1 μF which are connected in parallel.
Note 3: Utmost care is necessary in the design of the output, VCC, VM, and GND lines since the IC may be destroyed
