General Description

The BL2046 is a 4-wire touch screen controller which supports a low-voltage I/O interface from 1.5V to 5.25V. The BL2046 has an on-chip 2.5V reference that can be used for the auxiliary input, battery monitor, and temperature measurement modes. The reference can also be powered down when not used to conserve power. The internal reference operates down to 2.7V supply voltage, while monitoring the battery voltage from 0V to 6V.

The BL2046 is a highly integrated controller for portable applications with 4-wire resistive touch panel such as, PDA, portable instruments, cellular phone, etc. The BL2046 is available in QFN-16 package.

Applications

􀂉 Cellular phones

􀂉 Personal digital assistants

􀂉 Touch screen monitors

􀂉 Portable instruments
