Toshiba Semiconductor and Storage TB62216FNG,C8,EL

Overview

TB62216FNG,C8,EL from Toshiba is a PWM chopper-type dual H-bridge motor driver IC fabricated in BiCD process, rated for 40 V/2.5 A per bridge, with integrated voltage regulator enabling single VM supply operation and internal current-sense feedback for constant-current control of two DC brushed motors.

For engineers reviewing the TB62216FNG,C8,EL datasheet, TB62216FNG,C8,EL pinout, TB62216FNG,C8,EL application, or TB62216FNG,C8,EL equivalent, key selection considerations include its dual-bridge PWM chopper architecture, programmable digital blanking time (TBLK), thermal shutdown (TSD) and over-current shutdown (ISD) protection, and HTSSOP48 package with 0.5 mm pitch for compact motor control designs.

Technical Context

The TB62216FNG,C8,EL implements a dual independent PWM chopper control system using an internal oscillator (OSCM) with external RC tuning (f_OSCM = 1.2–2.0 MHz), yielding a chopping frequency f_chop = f_OSCM/16 (40–150 kHz typical). Each bridge supports four-phase excitation modes-charge, fast decay, slow decay, and mixed decay-with digitally configurable blanking time (TBLK_A/B) to suppress current-sense noise during switching transients.

Current regulation is achieved via external sense resistors (RRS) and internal VREF (GND to 4.0 V), with gain rate 1/5.1; output current threshold is calculated as I_OUT = V_REF × 5.1 / R_RS. Protection includes thermal shutdown (Tj = 140–160 °C), ISD (2.6–4.6 A), VRS overvoltage detection (0.9–1.5 V), and power-on reset (VMPOR = 6.0–8.0 V, VCCPOR = 2.0–4.0 V).

FAQ

What is the maximum continuous motor current supported by the TB62216FNG,C8,EL?

The TB62216FNG,C8,EL supports 2.0 A continuous output current per H-bridge at Ta = 25°C, derated linearly above that ambient temperature. This rating assumes proper PCB thermal design (e.g., 2-layer board with 100 mm × 110 mm copper area) and accounts for R_ON(D-S) = 1.0 Ω conduction loss. Exceeding 2.0 A continuously risks triggering thermal shutdown or exceeding absolute maximum junction temperature (150 °C).

How does the digital blanking time (TBLK) function in the TB62216FNG,C8,EL?

The TB62216FNG,C8,EL uses TBLK_A and TBLK_B pins to configure digital blanking time: low level selects OSCM×4clk (2.5 µs), high level selects OSCM×6clk (3.75 µs). This blanking window disables current-sense comparison during H-bridge switching transitions, preventing false overcurrent trips caused by transient voltage spikes on the RS pins. It operates independently per bridge and is synchronized to the internal oscillator.

Can the TB62216FNG,C8,EL operate with only a single power supply?

Yes, the TB62216FNG,C8,EL integrates an internal voltage regulator that generates 5.0 V (±2.5%) from the VM supply, allowing full operation-including logic inputs, oscillator, and protection circuits-with only the VM rail (10–38 V). No separate VCC supply is needed, simplifying power design and reducing external component count.

What protection features are built into the TB62216FNG,C8,EL?

The TB62216FNG,C8,EL includes thermal shutdown (TSD, 140–160 °C), over-current shutdown (ISD, 2.6–4.6 A), RS pin overvoltage detection (VRS det, 0.9–1.5 V), and power-on reset (POR) for both VM and VCC rails. All protections force output disable and require POR reassertion to resume operation, ensuring fail-safe behavior during fault conditions.

How is motor current regulated in the TB62216FNG,C8,EL?

The TB62216FNG,C8,EL regulates motor current using PWM chopper control: the internal comparator compares voltage across external sense resistors (RS_A/RS_B) to a reference derived from VREF (gain = 1/5.1). When current exceeds the threshold (I_OUT = V_REF × 5.1 / R_RS), the PWM duty cycle is reduced to maintain constant average current, enabling precise torque control without external feedback loops.
