Toshiba Semiconductor and Storage TBD62004AFWG,EL

Overview

TBD62004AFWG,EL from Toshiba Electronic Devices & Storage Corporation is a 7-channel sink-type DMOS transistor array IC designed for driving inductive loads such as relays, solenoids, and small DC motors. It features built-in clamp diodes per channel, 50 V output voltage rating, 500 mA per channel maximum output current, and requires ≥7.0 V input to turn on-optimized for industrial control interfaces with TTL/CMOS-compatible logic levels.

For engineers reviewing the TBD62004AFWG,EL datasheet, TBD62004AFWG,EL pinout, TBD62004AFWG,EL application, or TBD62004AFWG,EL equivalent, this page delivers verified electrical specs, thermal derating guidance, real-world switching timing (t_ON = 0.4 µs, t_OFF = 0.8 µs), package footprint details (P-SOP16-0410-1.27-002), and validated alternative options for relay driver replacement scenarios.

Technical Context

The TBD62004AFWG,EL implements seven independent N-channel DMOS sink drivers with integrated reverse-biased clamp diodes across each output-to-COMMON path-enabling safe commutation of inductive loads without external flyback components. Its input threshold is fixed at ≥7.0 V (ON) and ≤1.0 V (OFF), eliminating ambiguity in high-noise industrial environments.

Each channel operates with low on-resistance (R_ON ≈ 2.0 Ω typ. at I_OUT = 100 mA, V_IN = 7.0 V), supports up to 50 V common-mode voltage at the COMMON pin, and sustains 400 mA continuous output under 10% duty cycle at T_a = 85°C when mounted on JEDEC 2s2p board-validated by absolute maximum ratings and operating range data.

FAQ

What is the minimum input voltage required to turn on a channel of the TBD62004AFWG,EL?

The TBD62004AFWG,EL requires a minimum input voltage of 7.0 V at any of pins I1–I7 to guarantee channel activation under all operating conditions (−40 to +85°C). This high threshold improves noise immunity in electrically noisy industrial settings compared to lower-threshold alternatives like the TBD62003A series. The TBD62004AFWG,EL does not activate reliably below this value-even at room temperature.

Does the TBD62004AFWG,EL include overcurrent or thermal protection?

No, the TBD62004AFWG,EL does not include built-in overcurrent, short-circuit, or thermal shutdown protection. As stated in Toshiba's official documentation, external fusing and current-limiting design are mandatory to prevent destruction during fault conditions. This design choice prioritizes simplicity and predictable behavior in systems where protection is implemented at the board or subsystem level-not within the IC itself. Always refer to the TBD62004AFWG,EL absolute maximum ratings before finalizing your protection scheme.

How is the COMMON pin used in the TBD62004AFWG,EL circuit?

The COMMON pin (Pin 9) serves as the common anode connection for all seven internal clamp diodes. It must be connected directly to the positive supply rail of the inductive load (e.g., +24 V), not to GND or V_CC. This configuration allows energy stored in the coil to safely recirculate through the diode when the output turns off. Incorrect COMMON connection-such as tying it to GND-will disable clamp functionality and likely destroy the TBD62004AFWG,EL during inductive switching.

What is the maximum continuous output current per channel for the TBD62004AFWG,EL at 85°C ambient?

At T_a = 85°C, the TBD62004AFWG,EL supports up to 390 mA per channel with 10% duty cycle and JEDEC 2s2p board layout, or 170 mA with 50% duty cycle under same conditions. These values are specified in Toshiba's Operating Ranges table (Page 4) and assume proper thermal design. Exceeding them risks junction temperature exceeding 120°C, triggering irreversible degradation. Derating is required above 25°C at 10 mW/°C.

Can the TBD62004AFWG,EL replace the ULN2803A in existing designs?

The TBD62004AFWG,EL is not a pin-compatible drop-in replacement for the ULN2803A due to differing pin counts (16 vs. 18), pin assignments (e.g., COMMON location), and package dimensions (P-SOP16 vs. SOIC-18). While both are 7/8-channel sink drivers with 50 V/500 mA ratings, substituting the TBD62004AFWG,EL requires PCB layout revision. However, its 7.0 V input threshold and JEDEC-qualified thermal performance make it a functional upgrade for new designs targeting higher noise immunity and better thermal headroom.
