53208 依据电压比较器高低电平判决的基本原理，结合精确电流采样支路，设计了一种固定限流装置。 With the basic principle of voltage comparator’s judgment for high or low voltage level of combined with accurate current-sampled branch, a constant-current device is designed.
53209 此外，通过第二条电流采样支路，达到返送（foldback）功能，使得短路电流不到最大负载电流的 10%，有效降低了 LDO（Low Drop-out）系统的过流关断功耗。 Furthermore, the function of foldback is achieved by the second current-sampled branch, the short-circuit current is below to the 10% of maximum load current, which effectively reduces the over-current shut-down power dissipation of LDO systems.
53210 基于 CZ6H 0. 35μm 标准 CMOS 工艺，应用 Cadence 工具进行仿真，结果显示，该过流保护电路可以把稳压器的最大输出电流限定在 300mA，输出短路电流不到 20mA，在无片外电容的条件下，系统表现出良好的瞬态响应效果; Based on CZ6H 0. 35m standard CMOS technology, simulated by the use of Cadence tool, the result reveals that the over-current protection circuit can limit the maximum at 300mA and the short-circuit current is below to 20mA. Under the capacitor-free condition, the LDO system shows favorable transient response.
