In one embodiment, a charging circuit for a capacitance has a first connection (8) for supplying a supply voltage (Vbat), a second connection (9) for connection to the capacitance (SC), a charging switch (S) which is coupled to the first and second connections (8, 9), and a temperature unit (TMU) with an output (13) which is coupled to a control input of the charging switch (S). The temperature unit (TMU) is set up to control the charging switch (S) on the basis of a difference between an instantaneous temperature (Tist) of the charging circuit and an adjustable upper limit value temperature (Tlimit) of the charging circuit. A method for charging the capacitance is also stated. |
