Infrared Driver
Description
The U426B is an IR-driver IC for IR data communication.
The circuit contains a programmable constant current
source (DRV) to drive the IRED. The current is pro-
grammed by an external resistor (R
S
). With the internal
comparator (COMP) an external voltage can be moni-
tored. The low-power standby mode, controlled by means
of the WAKE input, makes the circuit well suited for bat-
tery-powered systems.
Features
Programmable constant current 200 mA to 1.2 A
Signal frequency up to 500 kHz
Low-power standby mode
Internal voltage comparator
Wide voltage range 2.4 V to 12 V
