MITSUBISHI M54531P, M54531FP User Manual

MITSUBISHI SEMICONDUCTOR <TRANSISTOR ARRAY>

M54531P/FP

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.
