TA7612AP Datasheet Led Driver

Manufacturer: Toshiba

Overview: LED Driver TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA7612AP TA7612AP The TA7612AP is designed for 10 LED level meter driver.

General Description

Block diagram TA7612AP The above simplified TA7612AP Block Diagram is to give the general idea of the circuit's operation.

(1) General operation If VIN Voltage greater than the first threshold but less than the second threshold is applied “No.1” LED is lighted, if the input voltage is between the second and the third threshold, then 'No.1 and No.2' LED are in operation and so on.

(2) Adding R1 and R2 operation These resistors are to give the reference voltage of 10 parators.

Key Features

  • 10 LED's bar display driver.
  • Linear scale display.
  • Continuous 10 LED display.
  • By choosing a series connection of IC, can display more than 10 LED.
