Standard ICs

High voltage, high current Darlingtontransistor array

BA12001B / BA12003B / BA12003BF / BA12004B

The BA12001B, BA12003B, BA12003BF, and BA12004B are high voltage, high current, high sustain voltage transistorarrays consisting of seven circuits of Darlington transistors.

Because it incorporates built-in surge-absorbing diodes and base current-control resistors needed when using inductiveloads such as relay coils, attachments can be kept to a minimum.

With an output sustain voltage as high as 60V and an output current (sink current) of 500mA, this product is ideal for usewith various drivers and as an interface with other elements.

!Application notes

The BA12001B is a transistor array which can be directly coupled to a general logic circuit such as PMOS, CMOS, orTTL.

A current limiting resistor needs to be connected in series with the input.

The BA12003B / BF can be coupled directly to TTL or CMOS output (when operating at 5V). In order to limit the inputcurrent to a stable value, resistors are connected in series to each of the inputs.

The BA12004B is designed for direct coupling to CMOS or PMOS output using a 6 to 15V power supply voltage. In orderto limit the input current to a stable value, resistors are connected in series to each of the inputs.

The load for each of these products should be connected between the driver output and the power supply. To protect theIC from excessive swing voltage, the COM pin (Pin 9) should be connected to the power supply.Fig.6 shows the configuration of the on-chip diode for surge absorption.

In the construction of the surge-absorbing diode,there is an N-P junction between the N-layer (N-well + BL) and thesubstrate (P-sub) so that when the diode is on, current flows from the output pin to the substrate. In terms of the verticalconstruction, this diode is configured similar to a PNP transistor. When using the surge-absorbing diode, take appropriatemeasures regarding the thermal characteristics of the design considering the current that will be handled.

Also, if motor back-rush current or other conditions that will result continued surge current to flow to the surge-absorbingdiode can be foreseen, we strongly recommend connecting a Schottky barrier diode (or other type of diode with a lowfoward voltage) in parallel with the surge-absorbing diode to construct a bypass route for the surge current.
