The TLV803 family of supervisory circuits provides circuit initialization and timing supervision. The TLV853 and TLV863 are both functionally equivalent to the TLV803. These devices output a logic low whenever V_DD drops below the negative-going threshold voltage (V_IT–). The output, RESET, remains low for approximately 200 ms after the V_DD voltage exceeds the positive-going threshold voltage (V_IT– + V_hys). These devices are designed to ignore fast transients on the V_DD pin.
