Output Circuit
TA7288P
Output “H” Voltage
z Operation by Vref voltage
Voltage, which is applied to Vref, of which high output, 2VBE is applied to base A of the Q2 (power
transistor) and low voltage, Q2VBE is output as VOUT (H) by the Vref circuit.
VOUT = Vref+2VBE−Q2VBE
≒Vref+0.7 (V)
z Vref
Vref terminal required to connect to VS terminal for stable operation in case of no requirement of
VOUT control.
