Toshiba Electronics has a range of constant current LED drivers that provide ESD protection.

The TB62747 LED driver family feature 16 driver outputs with the ability to deliver constant currents of between 1.5mA to 45mA. ESD protection in accordance with Man Machine (MM) and Human Body (HB) models is ±500V and ±4000V respectively.

The drivers have a maximum current accuracy between outputs and between different devices of ±1.5%.

All TB62747 drivers operate with a supply voltage of between 3.3V and 5.0V and deliver output voltages up to 26V. Internally the devices are based around 16 channels of shift registers, latches, AND gates and the constant current outputs.

Control data format is serial-in, parallel-out. The devices are fully BiCMOS-compatible and can accommodate 3.3V and 5.0V input signals. A power-on-reset (POR) facility is also available.

The TB62747 drivers deliver fast output current response (tWOE(L) = 100ns min) and, when cascaded, support serial data transfer rates of 25MHz. Package options are  1.0mm pitch SSOP-24 (TB62747AFG), 0.65mm pitch SSOP-24 (TB62747AFNG) and 0.64mm pitch QSOP24 (TB62747AFNAG and TB62747BFNAG).
