NiCad_charger_for_grounded_batteries

Figure 8-18 showp a thermally based NiCad charger for use with batteries that are common to ground. The transistor is connected as a common emitter, so the inputs to A1 are reversed. However, operation is the same as for the Fig. 8-15 circuit. Notice that in both the Fig. 8-15 and 8-18 circuits, the trimpot can be eliminated by specifying an LT1006 set (at manufacture) to the desired offset value. High-quality grounds must be used, and all ground returns must be brought directly back to the supply common terminal. LINEAR TECHNOLOGY, APPLICATION NOTE 37, PAGE 2.
