DRV8243-Q1 Automotive H-Bridge Driver with Integrated Current Sense and

Diagnostics

1 Features

3 Description

•

AEC-Q100 qualified for automotive applications:

– Temperature grade 1: –40°C to +125°C, T_A

Functional Safety-Capable

– Documentation available to aid functional safety

system design

40 V Abs Max, 4.5 V to 35 V operating range

VQFN-HR package: R_{ON_LS}+ R_{ON_HS}: 84 mΩ

HVSSOP package: R_{ON_LS}+ R_{ON_HS}: 98 mΩ

I_OUTMax = 12 A

PWM frequency operation up to 25 KHz with

automatic dead time assertion

Configurable slew rate and spread spectrum

clocking for low electromagnetic interference (EMI)

Integrated current sense (eliminates shunt resistor)

Proportional load current output on IPROPI pin

Configurable current regulation

Protection / Diagnostic features with configurable

fault reaction (latched or retry)

– Load diagnostics in both the off-state and on-

state to detect open load and short circuit

– Voltage monitoring on supply (VM)

– Over current protection

The DRV824x-Q1 family of devices is a fully

integrated H-bridge driver intended for a wide range

of automotive applications. The device can be

configured as a single full-bridge driver or as two

independent half-bridge drivers. Designed in Texas

Instruments' proprietary BiCMOS high power process

technology node, this monolithic family of devices in

a power package offer excellent power handling and

thermal capability while providing compact package

size, ease of layout, EMI control, accurate current

sense, robustness, and diagnostic capability. This

family also has identical pin function with scalable

R_ON(current capability) to support different loads.

•

The devices integrate a N-channel H-bridge, charge

pump regulator, high-side current sensing and

regulation, current proportional output, and protection

circuitry. A low-power sleep mode is provided to

achieve low quiescent current. The devices offer

voltage monitoring and load diagnostics as well

as protection features against over current and

over temperature. Fault conditions are indicated

on nFAULT pin. The devices are available in

two interface variants - hardware (HW) and SPI.

SPI interface device has two variant choices, "P"

for externally supplied logic supply, and "S" for

internally generated logic supply. The SPI variant

offers more flexibility in device configuration and fault

observability.

– Over temperature detection

– Fault indication on nFAULT pin

Supports 3.3-V, 5-V logic inputs

Low sleep current - 1μA typical at 25°C

SPI or Hardware interface variant option

Configurable modes to operate the device as:

•

– Single full bridge using PWM or PH/EN mode

– Two half-bridges using Independent mode

Device comparison table shows the complete

family

Typical loads include unidirectional and

bidirectional brushed DC motors, solenoids, relays

and other inductive or resistive loads.
