M54526P/FP
7-UNIT 500mA DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE
DESCRIPTION
M54526P and M54526FP are seven-circuit Darlington tran-
sistor arrays with clamping diodes. The circuits are made of
NPN transistors. Both the semiconductor integrated circuits
perform high-current driving with extremely low input-current
supply.
FEATURES
High breakdown voltage (BVCEO ≥ 50V)
High-current driving (Ic(max) = 500mA)
With clamping diodes
Driving available with PMOS IC output of 8-18V
Wide operating temperature range (Ta = –20 to +75°C)

FUNCTION
The M54526P and M54526FP each have seven circuits con-
sisting of NPN Darlington transistors. These ICs have resis-
tance of 10.5kΩ between input transistor bases and input
pins. A spike-killer clamping diode is provided between each
output pin (collector) and COM pin (pin 9). The output tran-
sistor emitters are all connected to the GND pin (pin 8).
The collector current is 500mA maximum. Collector-emitter
supply voltage is 50V maximum.
The M54526FP is enclosed in a molded small flat package,
enabling space-saving design.
3K
GND
The seven circuits share the COM and GND.
The diode, indicated with the dotted line, is parasitic, and cannot
be used.
