A dual output temperature compensated voltage reference includes a voltage reference circuit (201) having a first output (203) for providing a first signal (204) dependent on temperature, and a second output (207) for providing a second signal (208) dependent on the first signal (204). A temperature dependence of the first signal (204) has a slope opposite a temperature dependence of the second signal (208). A cooperative device (209), such as a resistive divider (309, 311), combines the first and second signals (204, 208) and provides a third signal (212) dependent on the first and second signals (204, 208). Preferably, this apparatus is applied in a charge regulator including fault detection (109). The charge regulator (109) generates a charge voltage (110) dependent on the first signal (204) and a fault detection function is dependent on the third signal (212).
