SLVSFJ1A – NOVEMBER 2021 – REVISED DECEMBER 2021

DRV8245-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

4.5-V to 35-V (40-V abs. max) operating range

VQFN-HR package: R_{ON_LS}+ R_{ON_HS}: 32 mΩ

HTSSOP package: R_{ON_LS}+ R_{ON_HS}: 40 mΩ

I_OUTMax = 32 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 and 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 a

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 three

variants - hardwired interface: HW (H) and two SPI

interface variants: SPI(P) and SPI(S), with SPI (P)

for externally supplied logic supply and SPI (S) for

internally generated logic supply. The SPI interface

variants offer more flexibility in device configuration

and fault observability.

– Over temperature protection

– Fault indication on nFAULT pin

Supports 3.3-V, 5-V logic inputs

Low sleep current - 1μA typical at 25°C

3 variants - HW (H), SPI (S) or SPI (P)

Configurable control modes:

•

– Single full bridge using PWM or PH/EN mode

– Two half-bridges using Independent mode
