Over Voltage Protection MOSFET Gate Driver IC
Description
TCK42xG series is Over Voltage Protection Gate Driver IC for
External N-channel MOSFET. This product support to MOSFET
operating in wide voltage line from 2.7 V to 28 V with various Over
Voltage Lock Out lineups. And this features low standby current,
less than 1 µA, built in charge pump circuit and MOSFET gatesource protection circuit. Package is very small and thin WCSP6G
(1.2 mm x 0.8 mm (typ.), t: 0.35 mm (max)). Thus this is suitable
for mobile, wearable system and power management circuit such
as load switch application.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant
change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating
conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the
appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling
Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated
failure rate, etc).

1.
Input and Output capacitor
An input capacitor (CIN) and an output capacitor (COUT) are recommended for the stable operation. And it is effective
to reduce voltage overshoot or undershoot due to sharp changes in output current and also for improved stability of the
power supply. When used, place CIN and COUT as close to VIN pin and VOUT pin to improve stability of the power supply.
2.
VCT pin
VCT pin is pull down connection to GND. VCT High level voltage must be under 5.5V VIH max.
3.
VGATE1,2 pin and VOUT pin
VGATE1 pin is connected to Gate of VIN side MOSFET. VGATE2 pin is connected to Gate of VOUT side MOSFET.
VOUT pin is connected to Source of VOUT side MOSFET. When the gate driver IC turns off state, VGATE1 terminal
voltage is close to VIN voltage dropped by parasitic diode forward voltage. This circuit works to protect over voltage for
VIN side MOSFET Gate-Source terminal. VOUT terminal works to protect VOUT side MOSFET as same circuit.
4.
Turn on recovery time after Over Voltage Lock Out (OVLO)
Once VIN is in normal voltage range after OVLO, the turn on recovery time is similar VGS ON time (tON).
5.
Under Voltage Lock Out (UVLO) and Over Voltage Lock Out (OVLO)
UVLO and OVLO are designed in these products, but these are not designed to constantly ensure the suppression of
the gate driver IC and external MOSFETs within operation limits. Depending on the condition during actual usage, it could
affect the electrical characteristic specification and reliability. To select external MOSFETs, please consider enough
electrical design margin. When using these products, please read through and understand the concept of dissipation for
absolute maximum ratings from the above mention or our ‘Semiconductor Reliability Handbook’. Then use these products
under absolute maximum ratings in any condition. Furthermore, Toshiba recommends inserting failsafe system into the
design.
