Brief Description
The KTD2037/2037B is a fully programmable, constant
current RGB LED driver with a flexible control interface.
The device is ideally powered from one-cell lithiumion/
polymer, 3-cell NiCd/NiMH/Alkaline batteries, or
systems with 3.3V or 5V supplies. It provides three
independent programmable constant current sinks without
requiring any external components.
With an on-chip timing control unit, LED blink rate, fade-in
and fade-out are user-adjustable resulting in unique color
lighting patterns.
Ten internal registers are programmed via the I2C control
interface with a built-in decoder allowing individual control
of the LED channels’ On/Off state and current level. A total
of 191 current levels are available for each channel from
0.125mA to 24mA with a 0.125mA step.
An AutoBlinQ mode automatically turns on and off LED1
(on D1 pin) at 8mA every 2s after EN pin goes high. In this
mode, a phone with a discharged battery connected to a
charger can have LED1 blink to notify that the battery is
charging.
In shutdown mode, the quiescent current is reduced to less
than 1μA.
The device is available in a low profile 8-pin 1.5mm x
1.5mm x 0.5mm Ultra-Thin DFN package. The package is
Pb-free and RoHS compliant.
