Supply Voltage Protection AI02169 VCC 0.1 µF DEVICE VCC VSS POWER SUPPLY DECOUPLING and UNDERSHOOT PROTECTION ICC transients, including those produced by output switching, can produce voltage fluctuations, re- sulting in spikes on the VCC bus. These transients can be reduced if capacitors are used to store en- ergy, which stabilizes the VCC bus. The energy stored in the bypass capacitors will be released as low going spikes are generated or energy will be absorbed when overshoots occur. A bypass ca- pacitor value of 0.1µF (as shown in Figure 12) is recommended in order to provide the needed fil- tering. In addition to transients that are caused by normal SRAM operation, power cycling can generate neg- ative voltage spikes on VCC that drive it to values below VSS by as much as one Volt. These nega- tive spikes can cause data corruption in the SRAM while in battery backup mode. To protect from these voltage spikes, it is recommended to con- nect a schottky diode from VCC to VSS (cathode connected to VCC, anode to VSS). Schottky diode 1N5817 is recommended for through hole and MBRS120T3 is recommended for surface mount. |
