Key System Specifications

Table 1-1 Key System Specifications
PARAMETER COMMENTS MIN TYP MAX UNIT
VIN Supply Voltage Battery Input 3(1) 12 36(1) V
Ppresence Power consumption in presence mode VIN = 12V 3.16 mW
Pgesture Power consumption in gesture mode VIN = 12V 272 mW
Even though LMR43620-Q1 supports a wide input voltage range of 3.0V to 36V with transients up to 42V, the recommendation is to operate the reference design under 3.6V to 20V for proper functional operation.
