High-Voltage Ideal Diode Controller with

Integrated CSA

MAX16170

The MAX16170 is available in a 4mm x 4mm x 0.75mm,

20-pin, side-wettable, TQFN package with an exposed

pad and operates over the automotive temperature

range of −40°C to +125°C.

General Description

The MAX16170, a high-voltage ideal diode controller,

offers full system-level protections for automotive

applications. The MAX16170 is designed to enhance

system safety, reliability, and performance with added

diagnostics, robust fault-recovery mode, and a high-

side, integrated current-sense amplifier (CSA). The

MAX16170 features dual-gate-driver topology that

supports common-drain configuration and protects

systems against reverse voltage, input overvoltage

(OV), undervoltage (UV), overcurrent, and thermal fault

conditions. During power-up, the device monitors the

health of the external power metal-oxide semiconductor

field effect transistors (MOSFETs) for open or short-

circuit conditions and asserts an open-drain output

(FETOK) when one or both power MOSFETs are

damaged. Additionally, the device offers an open-drain

fault output (FLT) that asserts low when there is a fault

condition.

Features and Benefits

•

AEC-Q100 Qualified for Automotive Applications

3V to 65V Operating Voltage Range

• Supports 12V/24V Battery Systems

•

−42V to +76V Input Protection Range

• Wider Transients Immunity

High-Side CSA

• Enables System Power-Level Measurement

Output Sensing

• Enables Fast Fault Recovery

30kHz Active Rectification

• Facilitates System Level Testing Per Automotive

Standard

During normal operation, the MAX16170 regulates the

voltage drop across the drain-to-source of MOSFET

(Q1) to 10mV to block DC flow to the battery in reverse

voltage fault condition. A resistor from a low-voltage

input (ILIM) to ground sets the overcurrent threshold.

•

Support ORing Application

Robust Fault-Recovery Mode

5µA Shutdown Mode Current

• Extends Battery Life

During sleep mode of operation, the device consumes

only 5uA (typ) while delivering 1mA (min) of current to

the load to support stand-by system operation. In

shutdown mode, the charge pump is disabled, and the

OV and UV resistive dividers are disconnected from the

battery through the TERM switch to lower the shutdown

supply current to 3µA (typ).

•

Resistor-Adjustable OCP Threshold

• Adds Design Flexibility

1mA (min) Sleep Mode Current Output

• Supports Standby Mode of Operation

FETOK/FLT Outputs

• Enhance System Diagnostics
