7-UNIT 400mA DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE
DESCRIPTION
M54531P and M54531FP are seven-circuit Darlington transistor 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
Á High breakdown voltage (BV
CEO≥ 40V)
Á High-current driving (Ic(max) = 400mA)
Á With clamping diodes
Á Driving available with PMOS IC output
Á Wide input voltage range (V
I = –40 to +40V)
Á Wide operating temperature range (Ta = –20 to +75°C)
APPLICATION
Drives of relays and printers, digit drives of indication elements (LEDs and lamps), and MOS-bipolar logic IC interfaces
FUNCTION
The M54531P and M54531FP each have seven circuits consisting of NPN Darlington transistors. A serial circuit including a diode and resistance of 20kΩ is provided 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 transistor emitters are all connected to the GND pin (pin 8).
The collector current is 400mA maximum. Collector-emitter
supply voltage is 40V maximum.
The M54531FP is enclosed in a molded small flat package,
enabling space-saving design.
