Why Peak Currents Matter in Bluetooth LE SoCs

When it comes to Bluetooth Low Energy (LE) System-on-Chips (SoCs), one of the key considerations is not just the overall current consumption but also the peak currents. These can be particularly problematic when using coin cells, which have a high internal resistance that increases over time. The CMT4531 by HopeRF addresses this issue head-on, ensuring that no excessive peak currents occur.
