5 Description (continued)

Accurate back-plane biasing is provided by a linear amplifier and can be adjusted either by an external resistor or the I2C interface. The VCOM driver can source or sink current depending on panel condition. For automatic VCOM adjustment in production line, VCOM can be set from –0.3 V to –2.5 V with 8-bit control through the serial interface. The power switch is integrated to isolate VCOM driver from E Ink® panel.

The TPS6518x and TPS65181xB devices provide precise temperature measurement function to monitor the panel temperature during operation. The TPS65180 and TPS65180B requires the host processor to trigger the temperature acquisition through an I2C write whereas the TPS65181 and TPS65181B automatically updates the temperature every 60 s.
