Santa Clara, Calif. — Catalyst Semiconductor, Inc., a provider of analog, mixed-signal devices and non-volatile memory, has expanded its I/O expander product line with CAT9532, a 16-bit LED driver with dimming and The flash control function can also be used as a normal I/O expander.
A direct replacement for the PCA9532, the CAT9532 provides the ability to drive up to 16 parallel LEDs for backlight and RGB color mixing applications, while providing 256 levels of dimming. This device can also individually turn on, off or flash each LED (the flashing frequency is available in two programmable options). In addition, the device can also be used for sensor control, power switch, switch button and status indicator illumination via I2C or SMBus interface. And other functions.
Product Features
Drive 16 LEDs and provide dimming
256-level brightness adjustment
16 open-drain outputs with 25mA per drive
Two programmable flashing frequencies:
- Frequency: 0.593Hz to 153Hz
- Duty cycle: 0% to 99.6%
I/O can be used as a general purpose I/O port
Compatible with 400kHz I2C bus specification
Package: 24-lead SOIC, TSSOP or 24 solder TQFN package (size 4x4mm)
Price and availability
The CAT9532 LED driver/flasher device is priced at $0.75 each when ordered in quantities of 10,000. Samples are available now. Production is expected to be delivered 6 to 8 weeks after receiving the order.
