The voltage gain [Gvo] is 1.0 [V/V]. The current gain is 2.0 [A/V] (at sensing resistor: 0.5 Ω and R1=, R2=0Ω) in forward torque directions, and the dead zone is from 0mV to 80mV (at R1=, R2=0Ω). The coil current gain under the reverse torque is the same with in forward torque directions. And the limitation function gets on when the differential voltage of VCC12 to RSL is 0.5V. Therefore current-gain-control and current-limit of this IC is determined with sensing resister value.

In switching the motor current direction, Phase delay circuit switch-off all output transistor of H-bridge for 3 μsec. 5) The built-in thermal shutdown circuit mutes the output current when the chip temperature reaches 175 ℃ (typ.). The hysteresis is set to 25 ℃ (typ.), so the circuit will start up again when the chip temperature falling to 150℃ (typ.).

In case the bias pin voltage is pulled down below 0.7V (typ.), the output current is muted. 7) Insert the bypass capacitor (~0.1 μF) between VCC pin and GND pin as close as possible. 8) Heat dissipation fins are attached to the GND on the inside of the package. Make sure to connect them to the external GND. 9) Wiring for RSL Considering the wiring resistance, connect each detecting resistor as close as possible to the current detection terminals for the sledge motor drive RSL 1 (pin3) and 2 (pin39) of the IC.
