1 / 9 page 1 ELM97xxxxB CMOS Voltage detector 9 - Parameter Symbol Limit Unit Power supply voltage Vdd 10 V Output voltage Vout N-ch : Vss-0.3 to +10 V CMOS : Vss-0.3 to Vdd+0.3 Output current Iout 50 mA Power dissipation Pd 500 (SOT-89) mW 250 (SOT-23) Operationg temperature Top -40 to +85 °C Storage temperature Tstg -55 to +125 °C ELM97xxxxB is CMOS voltage detector IC which consists of very-low-power-consumption reference voltage source, comparator, output driver, hysteresis circuit and detection voltage setting resistor. Because of positive logic output, the output becomes low level when Vdd is lower than detection voltage. There are 2 types of output style of ELM97 series: N-ch opendrain and CMOS output. ELM97 series can be made as semi-custom IC within the range of 0.9V to 5.5V(N-ch) and 1.6V to 5.5V(CMOS) by 0.1V step. • Detection voltage range • Low voltage operation • Low current consumption • Accuracy of detection voltage • Temperature coefficient • Package • Reset for microcomputers • Power voltage shortage detectors • Switch of backup power source • Battery checkers ELM97xxxxB-x Symbol a, b Detection voltage e.g. : 09: Vdetn=0.9V(N-ch) 24: Vdetn=2.4V(CMOS) 10: Vdetn=1.0V(N-ch) 30: Vdetn=3.0V(CMOS) 11: Vdetn=1.1V(N-ch) 45: Vdetn=4.5V(CMOS) c Output form N: N-ch(N-ch opendrain) C: CMOS d Package A: SOT-89 B: SOT-23 e Product version B f Taping direction S: Refer to PKG file N: Refer to PKG file ELM97 x x x x B - x ↑ ↑ ↑ ↑ ↑ ↑ a b c d e f ■General description ■Features ■Application ■Maximum absolute ratings ■Selection guide : N-ch 0.9V to 5.5V (by 0.1V) CMOS 1.6V to 5.5V (by 0.1V) : Reset operation assured at 0.8V : Typ.1μA(Vdd=1.5V) : ±2.5% : Typ.-300ppm/°C(Vdetn<2V) Typ.-100ppm/°C(Vdetn≥2V) : SOT-89, SOT-23 |
