TB62212FNG
TOSHIBA BiCD Process Integrated Circuit Silicon Monolithic
TB62212FNG
PWM Chopper Type Dual-Stepping Motor Driver
The TB62212FNG is a PWM chopper type dual-stepping motor driver.
Two stepping motor drivers can drive up to four brushed DC motors.
Incorporating two pairs of H-bridge drivers, the TB62212FNG can drive
two DC motors or a single stepping motor.

Single-chip motor driver for bipolar stepping motor control
Monolithic IC structured by BiCD process.
HTSSOP48-P-300-0.50
Weight: 0.21 g (typ.)
Low ON-resistance: R
on
= 2.2
(Upper and lower sum of P- and N-channel output transistors: Tj = 25 @0.6 A (typ.))
In large mode, ON-resistance of combined H-bridges is: R
on
= 1.1
(Upper and lower sum of P and N channel output
transistors: Tj = 25
@0.6 A (typ.))
Over-current detection (ISD), thermal shutdown (TSD) and V
M
power-on reset circuits
Since the IC incorporates a V
CC
regulator for internal circuit operation, an external power supply (5 V) is not required.
Package: Surface mount package with a backside heat sink: 0.5mm lead pitch)
Maximum output voltage:40 V
Output current: 2.0 A (max) in DC (S) mode:1.5 A (max) in Stepping (S) mode
Chopping frequency can be set by external capacitor. High-speed chopping is possible at 100 kHz or higher.

Note 1: GND wiring: We recommend that a heat sink be grounded at any parts, and the board and output pins be
grounded at only one contact point. Take the heat dissipation into consideration when designing the board.
When in controlling the setting pins for each mode by SW, those pins should be pulled up to power supply like
V
CC
or pulled down to GND not to go into a high-impedance (Hi-Z) state.
Utmost care is necessary in the design of the output line, V
M
line and GND line since IC may be destroyed due
to short-circuit between outputs, to supply, or to ground.
Especially for those pins that are connected to power supply and get a large current flow (such as V
M
, RS, OUT
and GND), they should be properly wired; otherwise troubles including destruction may occur to this IC. If the
logic input pins are not wired properly, malfunction that would destroy the IC may occur due to a large current
exceeding the absolute maximum ratings.
Care should be taken in the design of board layouts and implementation of the IC.

: In the modes that include DC (S) mode, the digital tBLANK time can be separately set for each axis pair, axes A and B
and axes C and D.
In DC (S)
×
4-axis control mode, the external short brake function cannot be used. Thus, the short brake operation
should be performed by using the IN1 and IN2 inputs.
The motor drive Mode(2, 1, 0) = (L, L, H) is provided only for Toshiba testing and must not be used during normal
operation.
Note 1: In Combination mode, such as Stepping (L) and DC (L) modes, the impedance outside the IC should be
balanced.
Note 2: In large mode, if the impedance of wiring to mutually connected output transistors is unbalanced, the current that
flows through the transistor also becomes unbalanced and may exceed the absolute maximum rating of the
transistor, thus permanently damaging the transistors.
