TA7612AP LED DRIVER

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.

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. Block Diagram (Note 1) Weight: 1.00 g (typ.) Note 1: (Vref max ( = PIN 15) = 3.6 V) 2 Pin Connection Terminated ground Terminated 1 kΩ between ground Display Light on No.1 LED Lighted all LED Without lighted No.1 LED Light on No.1 LED Condition VIN = 0~0.4 V (typ.) VIN ≥ 3.6 V (typ.) VIN = 0~0.36 V (typ.) VIN ≥ 0.36 V (typ.) 1 2002-10-29 PD Calculation At 10 LEDs PD = VCC × ICC1 + VOL × IO × 10 (W) TA7612AP Note: VOL is: VOL = VCC .
