An external PNP transistor can also be used as the pass transistor instead of the P-channel MOSFET. Due to the low current gain of the current amplifier (CA), a high gain Darlington PNP transistor is required to avoid too much charging current error. The gain ofthe current amplifier is around 0.6mV. For eve ry 1 of base current, a 1.6mV of gain error shows up at the inputs of CA. With RPROG = 19.6k (lOOmV across RSENSE), it represents l.67% of error in charging current. |
