IC502 & IC504, Power Half Bridge (STA518)
Table 2. Functional Pin Status
Note: 1.The pin is open collector. To have the high logic value, it needs to be pulled up by a resistor.
2.To put CONFIG = 1 means connect Pin 24 (CONFIG) to Pins 21, 22 (Vdd) to implemented single BTL (MONO MODE) operation
for high current.
