Auxiliary Power for Sensor Application ■ Application Circuit CRSET • Noise cancelation • Sensor Load Typ. 7V, 5mA • CVREG : 10V, 10uF, 2012 Copyright ⓒ Seoul Semiconductor Co., Ltd. 20 www.seoulsemicon.com VI. Protection ① Over Temperature Protection (OTP) – Hysteresis Application Circuit The LED is off when the temperature exceeds 160°C and restarts when the junction temperature falls. If a capacitor is connected to VREG, the Acrich3.0 IC restarts by the VREG reset. CRSET • Noise cancelation • Need a CVREG for Hysteresis OTP in all operation mode Copyright ⓒ Seoul Semiconductor Co., Ltd. 21 www.seoulsemicon.com VI. Protection ② RSET Open/Short Protection When RSET Pin is opened, the Acrich3.0 is shut down, that is, all the LED output currents become zero. When RSET Pin is shorted to VN(-), all the output currents have its extremely low current level below a few hundreds of uA determined by the offset voltages of the amplifiers consisting the LED current sources. ③ VREG Short Protection When VREG Pin is shorted to VIN(-), the Acrich3.0 becomes shut down.
