MP6516
35V, 2.8A, ½-H control H-Bridge Motor
Driver in a TSSOP-16 EP Package
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP6516 is an H-bridge motor driver that
operates from a supply voltage up to 35V and
delivers a motor current up to 2.8A. Typically,
the MP6516 is used to drive a DC brush motor.
For the MP6516, control of each half-bridge is
independent, using IN1, IEN1, IN2, and EN2
pins.
An internal current-sensing circuit provides an
output voltage proportional to the load current.
The MP6516 also has cycle-by-cycle current
regulation and limiting. These features do not
require the use of a low-ohm shunt resistor.
Full protection features include over-current
protection (OCP), input over-voltage protection
(OVP), under-voltage lockout (UVLO), and
thermal shutdown.
The MP6516 is available in a 16-pin TSSOP-EP
(5.0mmx6.4mm) with an exposed thermal pad.

NOTES:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-toambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation produces an excessive die temperature, causing
the regulator to go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.

MP6516 – 35V, 2.8A, ½-H CONTROL, H-BRIDGE MOTOR DRIVER IN TSSOP-16 EP
OPERATION
The MP6516 is an H-bridge motor driver that
integrates four N-channel power MOSFETs with
2.8A of peak current capability. The MP6516
operates over a wide 5.4V to 35V input voltage
range and is designed to drive bipolar stepper
motors, DC brush motors, solenoids, or other
loads.
Current Sensing
The current flowing into the two low-side
MOSFETs (LS-FET) is sensed with an internal
current sensing circuit. A voltage proportional to
the output currents is sourced on VISEN.
VISEN output voltage scaling is set by a
resistor connected between ISET and ground.
For 1A of output current, 100µA of current is
sourced into the resistor connected to ISET. For
example, if a 10kΩ resistor is connected
between ISET and ground, the output voltage
on VISEN is 1V/A of output current. Current is
sensed when one of the LS-FETs is turned on.
The load current applied to VISEN should be
kept below 2mA with no more than 500pF of
capacitance.
Current Limit and Regulation
The current in the outputs is limited using
constant-off-time pulse-width modulation (PWM)
control circuitry. Initially, a diagonal pair of
MOSFETs turns on and drives current through
the load. The current increases in the load,
which is sensed by the internal current-sense
circuit. If the load current reaches the current
trip threshold, the entire H-bridge switches to a
high impedance with all MOSFETs turned off.
After a fixed off-time (tITRIP), the MOSFETs are
re-enabled, and the cycle repeats.
Note that the current is sensed only in the LSFETs. If the outputs are used to drive a load
that is connected to ground directly, the current
regulation and current measurement do not
function.
The current limit threshold is reached when
VISET reaches 1.5V. For example, with a 10kΩ
resistor from ISET to ground, the VISET voltage
is 1V/A of the output current. Therefore, when
the current reaches 1.5A, the VISET voltage
reaches 1.5V, and a current trip occurs.
MP6516 Rev. 1.02
9/20/2017
Blanking Time
There is often a current spike during turn-on
due to the body diode’s reverse-recovery
current or the shunt capacitance of the load.
This current spike requires filtering to prevent it
from shutting down the high-side MOSFET (HSFET) erroneously. An internal, fixed, blanking
time (tOCPD) blanks the output of the current
sense comparator when the outputs are
switched. This blanking time also sets the
minimum on time for the HS-FET.
Input Logic
For the MP6516, control of each half-bridge is
independent, using IN1, IEN1, IN2, and EN2
(see Table 1).

nSLEEP Operation
Driving nSLEEP low puts the MP6516 into a
low-power sleep state. In this state, all internal
circuits including the gate drive charge pump
are disabled, and the H-bridge outputs are
turned off. All inputs are ignored when nSLEEP
is active low. When waking up from sleep mode,
approximately 1ms of time must pass before
the outputs operate.
Fault Indicator (nFAULT)
The MP6516 provides an nFAULT pin that is
driven active low if any of the protection circuits
are activated. These fault conditions include
over-current, over-temperature, and overvoltage. nFAULT is also driven low when a
current-limit trip occurs. nFAULT is an opendrain output and requires an external pull-up
resistor. When the fault condition is removed,
nFAULT is pulled inactive high by the pull-up
resistor.
Over-Current Protection (OCP)
The over-current protection (OCP) circuit limits
the current through each MOSFET by reducing
the gate drive voltage to the MOSFET. If the
MOSFET remains in the current-limit condition

for longer than the over-current deglitch time, all
MOSFETs in the H-bridge are disabled, and
nFAULT is driven low. The driver remains
disabled for tOCP and is re-enabled automatically.
Over-current conditions are sensed on both
high- and low-side devices. A short to ground,
supply, or across the motor winding results in
an over-current shutdown. Note that OCP does
not use the current sense circuitry used for the
PWM current control and is independent of the
ISET resistor value.
Over-Voltage Protection (OVP)
If the input voltage applied to VIN is higher than
the OVP threshold, the H-bridge output is
disabled, and nFAULT is driven low. This
protection is released when VIN drops to a safe
level.
MP6516 Rev. 1.02
9/20/2017
Input Under-Voltage Lockout (UVLO)
If the voltage on VIN falls below the undervoltage lockout (UVLO) threshold at any time,
all circuitry in the device is disabled, and the
internal logic is reset. Operation resumes when
VIN rises above the UVLO threshold.
Thermal Shutdown
If the die temperature exceeds safe limits, all
MOSFETs in the H-bridge are disabled, and
nFAULT is driven low. Once the die
temperature has fallen to a safe level, operation
resumes automatically.
