FEDL8511-05 Issue Date: March 08, 2013 ML8511 UV Sensor with Voltage Output GENERAL DISCRIPTION The ML8511 is a UV sensor, which is suitable for acquiring UV intensity indoors or outdoors. The ML8511 is equipped with an internal amplifier, which converts photo-current to voltage depending on the UV intensity. This unique feature offers an easy interface to external circuits such as ADC. In the power down mode, typical standby current is 0.1A, thus enabling a longer battery life. FEATURES • Photodiode sensitive to UV-A and UV-B • Embedded operational amplifier • Analog voltage output • Low supply current (300A typ.) and low standby current (0.1A typ.) • Small and thin surface mount package (4.0mm x 3.7mm x 0.73mm, 12-pin ceramic QFN) APPLICATIONS • Smart phone, Watch, Weather station,Bicycle navigation, Accessary, Gaming BLOCK DAIAGRAM TP V EN DD 9 7 4 Amplifier OUT 8 UV Photo- diode ML8511 5 10 GND TR PIN CONFIGURATIONS Pin Symbol I/O Function 7 VDD PW Supply voltage.

EN should be HIGH or LOW while V is applied. DD Output should be read after output voltage level becomes stable. Maximum time required until stable output voltage reaches is 1 millisecond after EN goes HIGH. V DD EN T SU OUT 5/8

FEDL8511-05 ML8511 PACKAGE DIMENTIONS (Unit: mm) Notes for Mounting the Surface Mount Type Package The surface mount type packages are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact our responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times). Specifications are defined without considering the UV absorption by an external cover material. Please contact our sales representativeus when the cover material is applied. Do not press or rub the surface of the resin covering the top of the package where, which is on the UV-ray is light received. In addition, do not apply pressure at high temperature. 6/8
