SLIS150E – MARCH 2014 – REVISED FEBRUARY 2016
Feature Description (continued)
7.3.5 Protection Circuits
The DRV5013 device is fully protected against overcurrent and reverse-supply conditions.
7.3.6 Overcurrent Protection (OCP)
An analog current-limit circuit limits the current through the FET. The driver current is clamped to I_OCP. During
this clamping, the r_DS(on) of the output FET is increased from the nominal value.
7.3.7 Load Dump Protection
The DRV5013 device operates at DC V_CC conditions up to 38 V nominally, and can additionally withstand V_CC =
40 V. No current-limiting series resistor is required for this protection.
7.3.8 Reverse Supply Protection
The DRV5013 device is protected in the event that the V_CC pin and the GND pin are reversed (up to –22 V).
NOTE
In a reverse supply condition, the OUT pin reverse-current must not exceed the ratings
specified in the Absolute Maximum Ratings.
FAULT
FET overload (OCP)
Load dump
Reverse supply
CONDITION
I_SINK ≥ I_OCP
38 V < V_CC < 40 V
–22 V < V_CC < 0 V

DESCRIPTION
Output current is clamped to I_OCP
Device will operate for a transient duration
Device will survive this condition
7.4 Device Functional Modes
The DRV5013 device is active only when V_CC is between 2.5 and 38 V.
When a reverse supply condition exists, the device is inactive.
RECOVERY
I_O < I_OCP
V_CC ≤ 38 V
V_CC ≥ 2.5 V
