| Standard ICs Interface driver for microcomputer peripheral and display devices BA13002F The BA13002F is a high current transistor array consisting of six circuits of Darlington transistors. Because it incorporates built-in surge-absorbing diodes and base current-control resistors needed when using inductive loads such as relay coils, attachments can be kept to a minimum. With an output withstanding voltage as high as 20V and an output current (sink current) of 320 mA, this product is ideal for use with various drivers and as an interface with other elements. *Applications lamps, relays and solenoids Drivers for LEDs, Interface with other elements *Featureswithstanding voltage (BVceo) of 20V. 1) Output 2) High output current (lo) of 320 mA (Max.). 3) High current transfer ratio (hFE) of 1000 (Min.). 4) Wide range of voltages (- 25 to 20 V) can be applied to input. 5) Equipped with output surge-absorbing clamp diode. (Note: Refer to the "Operation notes.") 6) Equipped with strobe input pin. *Absolute maximum ratings (Ta = 20C to + 75C) Parameter Power supply voltage Output withstanding voltage Output current Input voltage Strobe input voltage Clamp diode reverse voltage Clamp diode forward current Power dissipation (Ta = 25C) Operating temperature Storage temperature Symbol VCC VCEO IO VI VI (STB) VR (D) IF (D) Pd Topr Tstg 1C over 25C.

Figure 10 shows the configuration of the on-chip diode for surge absorption. In the construction of the surgeabsorbing diode, there is an N-P junction between the N-layer (N-well + BL) and the substrate (P-sub) so that when the diode is on, current flows from the output pin to the substrate. In terms of the vertical construction, this diode is configured similar to a PNP transistor. When using the surge-absorbing diode, take appropriate measures 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 surgeabsorbing diode can be foreseen, we strongly recommend connecting a Schottky barrier diode (or other type of diode with a low forward voltage) in parallel with the surge-absorbing diode to construct a bypass route for the surge current.
