ABSTRACT:
An intrinsically safe battery powered device (100) includes a housing (102), a battery receiving region (104), an intrinsically safe power supply (108, 110), and device electrical circuitry (112). The power supply (108, 110) uses energy from batteries (106) received in the batter receiving region (104) of the device (100) to power the circuitry (112). In one implementation, the power supply includes an intrinsically safe charge pump circuit.
