Function Table
Pin Name
Osc1
Osc2
Description
The Output H-bridge can be enabled and disabled by connecting the Osc1 pin to the GND and VDD
pins. The output can be left enabled by connecting the Osc1 pin to GND.
The RC network can be connected between the oscillator’s Osc1 and Osc2 pins to pulse the EL lamp
on and off.
VDD
Internal supply voltage.
REL-Osc
EL lamp frequency is controlled via an external REL resistor connected between the REL-Osc and GND
pins of the device.
VB
VB side of the EL lamp driver H-bridge. Connection for one of the EL lamp terminals.
VA
VA side of the EL lamp driver H-bridge. Connection for one of the EL lamp terminals.
HVIN
High voltage input supply pin.
GND
Ground pin.
