HL5239 GENERAL DESCRIPTION

HL5239 is a multiple point object proximity sensor IC, which can be used to determine position of an object in a keypad matrix, and can be called object position detector.

The sensors of the object position detector are composed of multiple arrays of sensor plates. The key matrix is formed by 7 columns and 4 rows which are connected to the inputs and outputs of HL5239. Each sensor consists of two metal plates, with one plate connected to one of the rows and the other plate connected to one of columns. Maximum of 28 key plates can be formed by this technology.

HL5239 is a mixed mode IC fabricated by CMOS technology. The signal at the keypad is input to sensor processor by column and row scanner and converted to digital data.

In order to expand the number of the keys, two or more IC can be used in one system. Besides, noise rejection circuit is built-in HL5239 to minimize the interference from outside system.

FEATURES

  • Mixed mode integrated circuit.
  • Low operating current
  • Built-in noise rejection circuit
  • Parameters can be programmed by external microprocessor
  • Keys of keypad are expandable
  • Built-in regulator circuit
