STP16CP05 is a low voltage 16-bit constant current LED sink driver from ST. It has features like low voltage power supply, 16 channels of constant current output, adjustable output current, can be driven by a 3.3V microcontroller, output current range 5-100mA, max clock frequency 30MHz, ESD protection 2.5kV HBM, 200V MM.
The STP16CP05 is a monolithic, low‑voltage LED driver that provides sixteen constant‑current output channels. Each channel can be programmed from 5 mA to 100 mA using an external resistor, and the device operates from a 3 V to 5.5 V supply. It features a high‑speed 30 MHz serial‑in, parallel‑out shift register and ESD protection of 2.5 kV HBM/200 V MM.
Key specifications include a 20 V output capability, operating temperature range of –40 °C to +125 °C, and a TSSOP24 package (exposed pad). The datasheet provides detailed pin descriptions, electrical ratings, timing diagrams, and recommended operating conditions for designers.
