IRSM836-084MA
7A, 250V
Integrated Power Module for
Small Appliance Motor Drive Applications
Description
IRSM836-084MA is a 7A, 250V Integrated Power Module (IPM) designed for advanced appliance motor
drive applications such as energy efficient fans and pumps. IR's technology offers an extremely compact, high
performance AC motor-driver in an isolated package. This advanced IPM offers a combination of IR's low RDS(on)
Trench MOSFET technology and the industry benchmark 3-phase high voltage, rugged driver in a small PQFN
package. At only 12x12mm and featuring integrated bootstrap functionality, the compact footprint of this surface-
mount package makes it suitable for applications that are space-constrained. Integrated over-current protection,
fault reporting and under-voltage lockout functions deliver a high level of protection and fail-safe operation.
IRSM836-084MA functions without a heat sink.

Fault Reporting and Programmable Fault Clear Timer
The IRSM836-084MA provides an integrated fault reporting output and an adjustable fault clear timer.
There are two situations that would cause the IRSM836-084MA to report a fault via the FLT pin. The first is an
under-voltage condition of VCC and the second is when the ITRIP pin recognizes a fault.
The fault clear timer provides a means of automatically re-enabling the module operation a preset amount
of time after the fault condition has disappeared. When a fault condition occurs, the fault diagnostic output (FLT)
stays in the low state until the fault condition has been removed and the fault clear timer expires; once the fault
clear timer expires, the voltage on the FLT pin will return to the logic-high voltage. Figure 4a is a block-level
diagram that focuses on the fault diagnostic and fault clear timer functionality of the driver chip within the module.
The fault clear timer is defined with a simple resistor-capacitor (RC) network on the RCin pin, as shown in Figure
4b.
Figure 5 is a timing diagram showing the states of the FLT and RCin pins during both normal operation and
under a fault condition. Under normal operation, both FLT and RCin are in high impedance (open drain) states.
CRCIN is fully-charged, and FLT is pulled up high. When a fault condition occurs, RCin and FLT are pulled low to
VSS – CRCIN is discharged; once the fault condition has been removed, RCin returns to a high impedance state
and the fault clear timer begins – that is, CRCIN starts charging via RRCIN. tFLTCLR seconds later – when the RCin
voltage crosses a datasheet-defined threshold of VRCIN,TH, FLT returns to a high impedance state and the module
is operational again. tFLTCLR is determined by a simple RC network, shown in Figure 6 - RRCIN and CRCIN determine
how long the voltage at the RCin pin takes to reach the VRCIN,TH fixed threshold.
