Functions and Features
• Output protection Zener diodes with variable breakdown voltages — When the Z1 and Z2 pins are open: VOLM = 57 V — When the Z1 and Z2 pins are shorted: VOLM = 32 V — An external Zener diode can be connected between Z1 and VCC. • Can support both 12-V and 24-V power supplies by changing an external resistor.
