20A/40V Integrated Power Module

in SIP23 package

The STK984-090A-E is a fully-integrated inverter power stage consisting

of a gate driver, six MOSFET’s and a high-side shunt resistor, suitable for

driving permanent magnet synchronous (PMSM) motors and brushless-

DC (BLDC) motors. The MOSFET’s are configured in a 3-phase bridge

with a single drain connection for the lower legs. The power stage has a

full range of protection functions including cross-conduction protection,

external shutdown and undervoltage lockout.

Voltage ringing due to stray inductance, especially in

occur during switching. Use layout techniques such as

Gate Driver Voltage: High-side and low-side

The high-side MOSFETs are driven with an internal charge pump. The gate voltage VG from the built-in charge pump

circuit is set at VG=VB1+12V.

Figure 8: Gate drive voltage variation with battery voltage for high-side MOSFETs

The gate drive voltage for the low-side MOSFETs follows the voltage on VB1. If VB1 exceeds 18.5V, the gate drive

voltage is limited to 17V.

STK984-090A-E

RESET input

An internal pull-up resistor (100k typical) is connected to the RESET signal. When the RESET pin is HIGH or left

open, the IPM operates normally. If the RESET line is LOW, all six gate driver outputs will be set to the OFF state.

When the short-circuit protection operates and latches the output OFF, the latched output OFF can be released by

setting the RESET input LOW and then HIGH again.

Figure 10: Timing diagram for RESET

www.onsemi.com

STK984-090A-E

Short-circuit Protection Circuit

The Short-circuit Protection Circuit monitors the drain voltage of the high side MOSFET to detect short circuits. This

circuit detects a short circuit when a short circuit current flows for longer than tspoff (typically 3μs). The outputs are

switched to the OFF state and the DIAG1 signal is switched HIGH. The IPM is then latched in the short-circuit

protection state. This state can be released by setting the RESET input LOW and then HIGH again.

Figure 11: Timing Diagram Short-circuit Condition

Over-current Protection Circuit

The Over-current Protection Circuit monitors the drain voltage of the low-side MOSFETs to detect over currents. This

circuit detects a short circuit when a short circuit current flows for longer than tocoff (typically 4.3μs). When a short

circuit is detected, the outputs are switched off and the short circuit condition is flagged by switching on DIAG1. The

over-current protection state is held for time t_INT(typically 1ms) then released. It is not latched like the short-circuit

current protection mode.

STK984-090A-E

Undervoltage Lockout Protection Circuit

The Undervoltage Lockout Protection Circuit monitors voltages supplied to VB1 pin to detect low voltages. When the

voltage on VB1 falls below the undervoltage lockout falling threshold, the outputs will be turned off. The undervoltage

lockout circuit has a hysteresis. If the voltage on VB1 rises above the undervoltage lockout rising threshold, the module

will return to normal operating mode.

Figure 13: Timing Diagram Low Voltage Protection

Overvoltage Protection Circuit

The Overvoltage Protection Circuit monitors the voltage on VB1. If the voltage on VB1 exceeds the overvoltage

protection threshold, the outputs will be switched off. The Overvoltage Protection Circuit has hysteresis. The IPM will

return to normal operation when the voltage on VB1 falls below the over-voltage protection falling threshold voltage.

STK984-090A-E

Over-temperature Protection Circuit

The Over-temperature Protection Circuit monitors the circuit substrate temperature to detect excessive temperatures.

When the case temperature rises above the temperature shutdown rising threshold, the outputs are switched off and the

over temperature condition is flagged on output DIAG2. There is hysteresis in the over-temperature protection circuit.

When the case temperature falls below the temperature shutdown falling threshold, the circuit returns to normal

operation and the over-temperature condition is no longer flagged on the DIAG2 output.
