small DC motors used in portable electronics. The 17510 can
operate efficiently with supply voltages as low as 2.0 V to as
high as 15 V, and it can provide continuos motor drive
currents of 1.2 A while handling peak currents up to 3.8 A. It
is easily interfaced to low-cost MCUs via parallel 5.0 V-
compatible logic. The device can be pulse width modulated
(PWM-ed) at up to 200 kHz. The 17510 has four operating
modes: Forward, Reverse, Brake, and Tri-Stated (High
Impedance).

Diagram, page 2, the 17510 is a monolithic H-Bridge with
built-in charge pump circuitry. For a DC motor to run, the
input conditions need to be set as follows: ENable input logic
HIGH, one INput logic LOW, and the other INput logic HIGH
(to define output polarity). The 17510 can execute dynamic
braking by setting both IN1 and IN2 logic HIGH, causing both
low-side MOSFETs in the output H-Bridge to turn ON.
Dynamic braking can also implemented by taking the ENable
logic LOW. The output of the H-Bridge can be set to an open-
circuit high-impedance (Z) condition by taking both IN1 and
IN2 logic LOW. (refer to
DC load current of up to 1.2 A. An internal charge pump
supports PWM frequencies to 200 kHz. The EN pin also
controls the charge pump, turning it off when EN = LOW, thus
allowing the 17510 to be placed in a power-conserving sleep
mode.
MOTOR SUPPLY VOLTAGE INPUT (VM)
the power sections of the IC. This supply then becomes
controlled and/or modulated by the IC as it delivers the power
to the load attached between OUT1 and OUT2. All VM pins
must be connected together on the printed circuit board with
as short as possible traces offering as low impedance as
possible between pins.
drops below the undervoltage threshold, the output power
stage switches to a tri-state condition. When the supply
voltage returns to a level that is above the threshold, the
power stage automatically resumes normal operation
according to the established condition of the input pins.
CONTROL SIGNAL INPUT AND ENABLE CONTROL
SIGNAL INPUT (IN1, IN2, EN)

inputs with hysteresis. The IN1, IN2, and EN work together to
control OUT1 and OUT2 (refer to
