EM MICROELECTRONIC-MARIN SA H6052 3-Pin Voltage Surveillance with Time-out Features n n n n n n n n n Proper microprocessor restart after power up Processor reset at power down On-chip oscillator gives a typical POR of 160 ms Reset output working down to 1.6 V No external components required Very small mounting space TO-92 package SOT-223 package Sensitivity typically 10 µs Typical Operating Configuration Description The H6052 is a CMOS device whichmonitors the supply voltage and controls the reset of the microprocessor. Upon the supply voltage rising above VTH ON, the reset output, whether RES or RES, will remain active (RES = 1, RES = 0) for an additional 160 ms. This allows the system voltage and the oscillator of the microprocessor system to stabilize before the system becomes fully active. When VDD drops below VTH OFF, the reset output goes active (RES = 1, RES = 0). Applications All microprocessor and microcontroller applications where an automatic restart of the micreoprocessor after power down is required: n n n n White goods Brown goods Automotive electronics Industrial electronics 1 H6052 Absolute Maximum Ratings Handling Procedures This device has built-in protection against high static voltages or electric fields; however, anti-static precautions precautions be taken as for any other CMOS component. Unless otherwise specified, proper operation can only occur when all terminal voltages are kept within the supply voltage range. Unused inputs must always be ti...
