The MAX803/NCP803 is a cost-effective system supervisor circuitdesigned to monitor Vcc in digital systems and provide a reset signal tothe host processor when necessary. No external components arerequired.
MAX 803/NCP 803是一種成本低廉的系統監控電路,用于監測數字系統中的VCC,并在必要時向主機處理器提供復位信號。沒有外部組件裝備。


The reset output is driven active within 10 usec of Vcc fallingthrough the reset voltage threshold. Reset is maintained active for atimeout period which is trimmed by the factory after Vcc rises abovethe reset threshold. The MAX803/NCP803 has an open drainactive- low RESET output. Both devices are available in SOT-23 andSC- 70 packages.
復位輸出通過復位電壓閾值在VCC下降的10 USEC內被激活。復位被保持為主動的,這是由工廠在VCC超過復位閾值后修剪的。MAX 803/NCP 803有一個打開的漏極-低復位輸出。這兩種設備都有SOT-23和SC-70封裝。


The MAX803/NCP803 is optimized to reject fast transient glitcheson the Vcc line. Low supply current of 0.5ụA (Vcc= 3.2 V) makethese devices suitable for battery powered applications.Features
MAX 803/NCP 803的優化是為了消除VCC線路上的快速瞬態故障。低電源電流0.5ụA(vcc=3.2V)使這些裝置適合于電池供電。
